摘　　要：研究了活性炭对水溶液中重金属离子铅镉铜的吸附行为,分析研究了ICP测定重金属铅镉铜的分析方法,并对分析的最佳条件进行了探讨。结果表明,100 mL溶液pH值为4.8,活性炭用量0.2000 g时,活性炭对Pb2+、Cd2+、Cu2+的最大吸附容量分别可达到52.54 mg/g、35.65 mg/g、57.05 mg/g。The adsorption behaviors of activated carbon for the heavy metals lead,cadmium and copper ion were studied,the analytical methods of heavy metals by ICP deter mination for lead,cadmium and copper was analysis,and the optimal analysis conditions were discussed.The results showed that 100 mL solution pH 4.8,the amount of 0.200 0 g of activated carbon,the adsorption capacity of activated carbon for Pb^2＋,Cd^2＋ and Cu^2＋ was 52.54,35.65 and 57.05 mg/g respectively.
