摘要
Using carboxymethyl chitosan （CM-CTS） as snake resin, B-62 resin crosslinked by,triethylenetetramine （TETA） as cage resin, a series of novel snake-cage type resin weresynthesized. Such factors as the best synthetic conditions, the swelling and regenerationproperties, and the sorption capacities of the above mentioned resins for metal ions wereinvestigated. The experimental results show these resins have good swelling propertiesand mechanical stability and do not run off in organic and inorganic solvents. Thesorption capacities of them for Cu2+, Ni2+,Zn2+, and Pb2+ were 0.89, 0.54, 0.32, and0.22mmol/g, respectively.
