摘　　要：用α-酮戊二酸和氯乙酸对壳聚糖进行了化学改性,制备了一种新的吸附剂-羧酸化壳聚糖(CKCTS),研究了其重金属吸附性能,结果表明:CKCTS对某些重金属是一种高效的吸附剂,其对Cu^(2+),Cd^(2+)和Ag^+的饱和吸附量分别达到0.0346mg/m L、0.0118mg/m L和0.1050mg/m L.A new adsorbent-carboxylic acid,carboxylic chitosan( CKCTS),was prepared by chemical modification with α-ketoglutarate and chloroacetic acid. The adsorption properties of CKCTS were investigated and the results showed it's an effective adsorbent for some heavy metal ions. The saturated adsorbing capacities of CKCTS for Cu^(2+),Cd^(2+)and Ag^+ reached 0. 0346 mg/m L,0. 0118 mg/m L and 0. 1050 mg/m L respectively.
