摘　　要：以聚苯乙烯负载聚酰胺-胺型螯合树脂为吸附剂,确定了金属离子溶液的pH值及流速;洗脱液的流速、浓度及酸度等最佳柱实验条件,测定了以Na+、Mg2+、Ca2+、Ba2+、Ni2+、Cd2+、Pb2+、Cu2+、Zn2+等金属离子作为干扰离子时该吸附剂对Hg2+的回收率。实验结果表明,该树脂对Hg2+具有较高的吸附选择性,从二元金属离子混合液中对Hg2+的回收率达到85.3%以上。In this paper the optimum experimental conditio.ns were determined using polyamide-amine type chelating resin as adsorbent by the column method. The recovery of Hg^2＋ from binary metal ions solution was investigated. The experimental results showed that： the resin had high adsorption selectivity towards Hg^2＋. The recovery of Hg^2＋ from binary metal ions solution was more than 85.3%.
