Adsorption of Pb2+in Wastewater Using Cassava Cross-linking Carboxymethylated Starch
摘要
Abstract
The cross-linking carboxymethylstarch adsorbent was prepared by dry method using cassava starch ,mechanically activated for 60 min by a stirring-type ball mill ,as a starting material .The effects of substitution degree ( Ds ) of cross-linking carboxymethylstarch , solution pH , Pb2+ initial concentration ,adsorption time ,and the starch dosage on adsorption abilities of the cross-linking carboxymethylstarch for Pb2+ were investigated .The results indicate that the adsorption abilities of the cross-linking carboxymethylstarch for Pb2+ is good .T reated solution of containing Pb2+ by the cross-linking carboxymethylstarch (Ds =0 .763) ,the adsorption capacity for Pb2+ is 18 .6 mg/g ,and the adsorption rate for Pb2+ is 93 .1% ,w hen the dosage of the cross-linking carboxymethylstarch is 0 .10 g ,Pb2+ initial concentration is 40 mg/L ,solution pH is 7 .0 ,adsorption time is 40 min .关键词
