Introduction

Adavantages of DAI alumina include:

Aluminum oxide has been used many years as an adsorbent in column chromatography

The raw materials for the production of chromatography grade aluminum oxides are different aluminum hydroxides,

ex. Hydragillite. The dehydration temperate is between 400 and 500°C. After dehydration the oxide has to be packed

air-tight as quickly as possible to retain the activity grade I. Activity grades of aluminum oxide are between I and V.

For an exact adjustment of activities II to V defined amounts of water are added to aluminum oxide of activity grade I.

The resulting dry mixtures are left in closed system until the added water is distributed evenly by surface diffusion

and isothermal distillation. With occasional stirring this equilibrium is always reached after 24hours. In tightly closed

containers the activity grade is maintained for years.

The following procedure by G. Hesse(Z. anal. Chem.211(1965)5) is a useful rapid test for the activity. In a test tube a

few ml of 1% solution of triphenylchloromethane in absolute benzene are added to sample to the aluminum

oxide(about 1g). If the sample turns yellow , it still has activity I.

A water content as low as 0.5% will inhibit the colorization.

Alumina, by being amphoteric (acting either as a base or an acid as well as being configured as neutral) provides the

chromatographer the ability to separate a multitude of compounds over and above silica gels.

Alumina can act as a weak ion exchanger demonstrating anionic or cationic properties, while additionally acting as an

adsorbent. Alumina, due to its unique biological characteristics, is a special adsorbent for use in separation sciences.

DAI,s Alumina is at the forefront of Separation Technology. A major reason for the exponential growth in the use of

alumina for chromatography has been our contribution to standardize production process. Our efforts have resulted

in standardized grades of alumina having well controlled and defined.

Deactivation ProtocolsDynamic Adsorbents, Inc. Aluminas are unique products; e.g. Super I, std Act I etc: High activity Alumina is useful for

eluting polor samples in nonpolor solvents, and for the purification of solvents. Lower activities of Alumina can readily

be obtained by the addition of polor media, especially water. Thus , each problem can be resolved via the adjustment

of the sorption system, as required for each problem.

Super ActivityⅠSuper Activity I alumina are unique as DAI,s products:

they provide twice the capacity compared to Standard Activity I.: Surface modifications are available are “A”(Acid),

“B”(Basic), and “N”(Neutral).

Super Activity I alumina as constitute the starting material for the Dynamic Adsorbents line of Alumina. A special

feature of Super Activity I is absolutely constant deactivation behavior which is valid for the deactivation process as

well as which in contact with the chromatographic solvent.

Standard ActivityⅠAlumina Standard Activity I (Act I) is available with multiple surface modification, A, B and N that facilitate the separa-

tion of wide range of compounds. In addition to pH, the activity of the surface of Alumina can mediate the separation.

Adjusting the activity can be altered by simply changing the water content of the alumina. (Alternatively: other polar

media can replace the water)

☞ Use high activity alumina (Standard Act I, Super Act I) for the separation of polar samples in non-polar solvent

systems … and for the purification of solvents.

☞ Use lower activity alumina for less polar samples.

Deactivation ProtocolsBy the following procedures below, it is relatively easy to obtain the desired activity

Alumina RAlumina R is an Alumina which is used for purifying, separating and product formulations in the radio active field;

used for the production of various generators where on isotope is retained while the other is eluted. Mainly its

improved exchange properties and the constant elution behavior will contribute to its reliability.

DynaPharma™ Pyrogen (Alumina for pyrogen removal)Formerly named Alumina P, DynaPharma™ Pyrogen is a specially designed superior alumina for the removal of

endotoxins and pyrogens from bacterial cell culture systems.

The isolation of therapeutic molecules from bacterial cell growth is hampered by the need to remove endotoxins and

pyrogens. Many different commercial techniques are in place in an attempt to remove these endotoxins, which are

lipopolysaccharide components of bacterial cell walls.

DynaPharma™, using either column chromatography or batch processing methods has, proven to be a superior tool

for the isolation and removal of pyrogens. The surface of activated alumina may be chemically modified to help

enhance pyrogen removal. Furthermore, the amphoteric property of activated alumina offers unique purification

advantages allowing Alumina P to be used either as a single step or as part of a two step purification process for the

isolation and removal of endotoxins.

Dyna-Aqua Oil Sorb™Dyna-Aqua Oil Sorb™ (DA Oil Sorb™ ) was developed for the removal of crude oil from the Gulf of Mexico or sea

water by combining the two most powerful mechanisms for capturing the greatest amount of oil from surface water -

DAI Dyna-Aqua™ high adsorbent specialized alumina, and Hobbs Bonded Fibers' specialized cotton. For the first

time, alumina is being used to impregnate nonwoven fibers, providing a cost-effective and efficient method of remov-

ing oil from the ocean.

Dyna-Aqua™ UraniumProduced with DAI's unique, patented technology, Dyna-AquaTM Uranium results in a material with superior perfor-

mance and capacities - exhibiting high selectivity in the presence of competing ions with good kinetics over a broad

operating range. Designed and manufactured to address the pressing needs outlined by the Federal Statutes

monitored by the Office of Environmental Management, Department of Energy, Dyna-AquaTM Uranium provides a

more efficient means to remove effluent from groundwater and surface water at radioactive environmental waste

sites.

Dyna-AquaTM Uranium is a metal oxide composite with an effective size of greater than 600 microns, offered as

either granular or spherical granules. Because of its tailored design it exhibits high selectivity in the presence of

competing ions with good kinetics over a broad operating range. Dyna-AquaTM Uranium can be easily retrofitted into

conventional water treatment equipment or vessels.

Applications include a wide array of industrial, environmental, and commercial applications for removing inorganic

contaminants in groundwater and surface waters. DAI’s Dyna-AquaTM Uranium can be utilized or retrofitted easily

into conventional water treatment equipment or vessels. Regeneration options are available based on the application.

Dyna-Aqua™ CopperDyna-Aqua™ Copper is a specially designed activated alumina oxide which is recommended for the isolation and

removal of copper found in waste water in either a suspension or solution form.

Copper is produced as a byproduct of many industrial processes. Dyna-Aqua Copper is designed especially for the

recovery of copper from spent solutions produced in printed circuit (wiring) board manufacture and electroplating.

It is currently thought that one difficulty in the commercial removal of copper from solution is that the metal forms into

complexes such as with benzotriazoles or other triazoles. Activated alumina oxides are able to address this issue and

remove the complex by the process of adsorption with high efficiency. Adsorption is defined as the interphase trans-

fer of material from a homogeneous or heterogeneous fluid matrix onto a solid surface.

Unlike organic pollutants, the major of which are susceptible to biological degradation, copper is not biodegradable

into a nontoxic end product. It must be reduced to acceptable levels prior to being discharged into the environment in

order for manufacturers to be in compliance with the Federal Clean Water Act, with the federal regulatory limit for

discharged copper in suspension or solution being 1.3 mg/Liter.

Furthermore competitive commercially available technologies such as ion exchange, chemical precipitation, ultafiltra-

tion and electrochemical deposition are costly – chelating and ion exchange resins are expensive.

The ideal solution to clean up of industrial wastewater would be to find an adsorbent which could avoid the need for

co-precipitation and pH adjustment. The sorption of copper is highly pH dependent with an increase in the amount of

adsorption with increasing pH.

The amphoteric property of specialty activated alumina is able to do away without the need for the coprecipitant, and

the compound is able to enhance copper removal as the pH of the solution increases.

Dyna-Aqua™ LeadDyna-Aqua™ Lead is a custom designed large particle activated alumina based metal oxide for the removal of lead

from industrial wastewater with an effective size of greater than 200 microns. It is specifically designed, modified and

chemically treated in order to enhance the removal of dissolved lead from a water stream. It is ideal for point of use

applications and more cost efficient and less energy intensive than reverse osmosis, the only other commercially

available point of use technology. Dyna-Aqua Lead offers a cost efficient, simple and reliable solution for municipal,

industrial and home use needs.

Dyna-Aqua™ Lead provides benefits superior to either chemical precipitation or ion exchange, commercial tech-

niques which are costly due to the high cost of required chemicals.

Lead transported through the water system comes from:

• Lead piping

• Lead solder

• Stabilizers used in the extrusion of PVC piping

• Brass fittings which are composed of copper, zinc and lead corroding when chloramines are used to disinfect

water, leading to the production of ammonia

Lead levels are monitored by the Environmental Protection Agency and cumulative exposure can lead to irreversible

damage to the gastrointestinal, hematologic and nervous systems and may cause death.

Water characteristics promoting the corrosion of water include low pH, low total dissolved solids, high water tempera-

ture and high concentrations of dissolved gases such as oxygen or carbon dioxide.

Adsorption results show pH dependency with a Freundlich isotherm fit. Activated alumina possesses both Lewis and

Bronsted acidic and basic sites. While being amphoteric alumina works best for lead removal when the pH of the

aqueous stream is in the pH range of 5.5 to 6.0.

Dyna-Aqua™ FluorideThis wide pore specialized activated alumina is designed to address municipal and industrial waste water needs.

High concentrations of natural fluorides are of significance in some regions of the United States including New

Mexico, West Texas, Colorado, Indiana and Illinois. Additionally fluorides are a waste product in association with

glass manufacturing, electroplating, and the production of steel and aluminum, pesticides, fertilizer and semiconduc-

tor manufacturing.

The maximum contaminant level for fluoride established by the Environmental Protection Agency is established at 4

parts per million, with a secondary standard set at 2 parts per million. Removal of fluoride from municipal and indus-

trial waste water may be obtained by precipitation, as well as membrane and adsorption processes.

The best way, bar none, to reduce the concentration of fluoride to 1 part per million or less is through adsorption onto

specially designed wide pore size activated alumina.
