A Study of Adsorption Property of Natural Polymer Chitosan as Adsorbent

HUANG Jin-ming, JIN Xin-rong (Department of Chemistry, East China Institute of Chemical Technology, Shanghai, 200237)  
Chitosan and the particles of its crosslinked derivatives were manufactured,and the adsorption properties for Hg2+ ,Cu2+ , Ag+ and Pd2+ were studied in this paper. The result indicates that the particles keep its rigidity in the acidic solution,the capacity for Pd2+ is 480 mg/g, and it has an adsorption selectivity to Pd2+ when Cu2+ and Pd2+ are present simultaneously in the solution. These particles could be used in collecting precious metals from waste water.
