Martin Smalley, Clay Swelling and Colloid Stability, CRC Taylor & Francis, Boca Raton, FL, 2006, 249 pp.
This book is commended to readers interested in an overviewof clay chemistry and mineral structure with emphasis on col-loidal clay, particularly vermiculite.
Chapter 1 provides an introduction to the subject, as illus-trated by research into the behavior of quaternary-ammonium-substituted vermiculite. Chapter 2 offers a theoretical under-standing of clay colloid stability in terms of coulombic at-traction and repulsion. Chapter 3 describes the force-versus-distance behavior of plate macroions, ionically charged clayplatelets. Chapter 4 describes and interprets the membraneequilibrium behavior of interacting plate macroions. Chapter 5describes clay swelling in response to exposure to fluids, as elu-cidated by use of experimental techniques such as small-angleneutron scattering. Chapter 6 presents an exact mean field the-ory to explain the stability behavior of clay colloids. Chapter 7reconsiders, in an interesting discussion, the “derivations of theHelmholtz and Gibbs free energies of ionic solution, in the orig-

inal Debye–Hückel theory.” Chapter 8 reviews neutron scatter-ing studies of the structure of clay plate macroions in solution,particularly vermiculite gels. Chapter 9 explores counterion dis-tribution between charged clay plates in solution. Chapter 10describes the collapse of clay colloids that occurs when ver-miculite gels are frozen. Chapter 11 summarizes the effects ofadding polymers to vermiculite systems. Chapter 12 describesthe steric influences on colloids due to polymer adsorption ontothe surfaces of colloid particles, that is, polymer-bridging floc-culation. The book includes about 258 literature references anda thorough subject index.
This is a delightful book, lucid and informative.
