Cotton Stalk Cellulose Modification Ⅲ. Preparation and Adsorption Property of Cotton Stalk Cellulose Modified by Poly (ethyleneamine)
Abstract:
Two modified cotton stalk cellulose derivatives (CEN-1, CEN-2) were prepared by reaction of epoxy-activated cotton stalk cellulose powder with diethylenetriamine or triethylene-tetramine, respectively.The effects of pH value of the solution on the adsorption properties of CEN-1 and CEN-2 to Pb2+, Hg2+, Cr3+ ions are discussed.
