摘要
用哌嗪和二硫化碳反应合成氨基二硫代甲酸中间体 ,再与二卤代烃反应得到 1 4 双 (二硫代酯基 )哌嗪聚合物 ,考察了中间体和螯合树脂对Ag+,Cu2 +,Zn2 +,Ni2 +,Co2 +,Pb2 +,Pd2 +,Cr3+的静态吸附性能 .结果表明 ,两者均可以吸附金属离子 ,缩聚后的螯合树脂具有更强的吸附能力 .
Two sorbents(Pzdtc,Resin)were synthesized by the reaction between di(alkyldithioate)piperazine and dichloroethane repspectively.The sorption and selectivity properties of two sorbents for Ag +,Cu 2+ ,Zn 2+ ,Cd 2+ ,Co 2+ ,Ni 2+ ,Pb 2+ ,Pd 2+ were also determined.In general,the two sorbents have high sorption capacities for metal ions and resin have better sorption and selectivity properties.
