摘　　要：通过活性炭纤维对镉离子的吸附实验,研究了活性炭纤维对镉离子的吸附性能,探讨了在静态条件下,活性炭纤维的质量,溶液的初始浓度,吸附时间,体系的pH值对活性炭纤维吸附性能的影响。实验发现活性炭纤维对镉离子有较强的吸附性能,吸附率最高达85%。在所选择的条件范围内,活性炭纤维最佳质量为0.2 g,溶液的最佳初始浓度为200 mg/L,最佳吸附时间为90 min。Adsorption performance of activated carbon fibers （ACF） for cadmium ions was studied by the adsorption experiment. Under static state, effect of activated carbon fiber mass, cadmium ion initial concentration, adsorption time and pH on adsorption performance of activated carbon fibers was investigated. The results show that the activated carbon fiber has good adsorption performance for cadmium ions;the optimal operation conditions are as follows：ACF mass is 0.2g, cadmium ion initial concentration is 200mg/L, adsorption time is 90min;under above conditions, the adsorption rate can reach 85%.
