摘　　要：二乙烯基三胺基氧化纤维素(YXA2,3)作为双功能吸附剂,在纯水和透析液中对一定浓度的肌酐和砷(Ⅲ)进行了吸附实验。结果表明,实验温度为37℃,pH值为7的透析液中,当肌酐浓度为100 mg.mL-1时,动态吸附实验在8 h时达到吸附平衡,平衡时吸附容量为3.32 mg.g-1;在纯水溶液和透析液中,当砷(Ⅲ)浓度都为2.0μg.mL-1时,动态吸附实验均在6 h达到吸附平衡,平衡时吸附容量分别为78.3μg.g-1、67.3μg.g-1。The adsorption test of aldehyde groups and polyamimo groups on YXA2,3 for creatinine and As（Ⅲ） were carried in pure water and dialysate separately.The result indicated that when the dynamic adsorbing balance was achieved in 8 hours the adsorbing capacity for 100 mg·mL-1 of creatinin was 3.32 mg·g-1 in dialysate at 37 ℃ and pH 7,and when the dynamic adsorbing balance was achieved in 6 hours the adsorbing capacity for 2.0 μg·mL-1 of As（Ⅲ） was 78.3 μg·g-1 in pure water and 67.3 μg·g-1 in dialysate.
