CONCLUSION
• Very potential to adsorp Pb2+
• Optimum condition in pH 2 at 1000 ppm• Capacity to adsorp Pb2+ is14,49 mg/gram• Has fluctuative biosorption
SUGGESTION
Make Simillar particle sizeDo ActivationDo optimum interaction timeDo desorption sequential Do experiment with other metal besides Pb(II)
