摘要
对萃铟余液中锗的CL N2 35萃淋树脂分离进行了研究。以N2 35为萃取剂 ,酒石酸为络合剂 ,在流动相pH =1.5～ 2 .5 ,线性流速 1.30cm/min条件下锗的吸萃率可达 98%以上。CL N2 35树脂对锗的吸萃选择性好 ,Zn、Fe、Cu。
The separation of germanium from indium raffinate by N235 levextrel resin was described. Using N235 as extraction agent, tartaric acid as complexing agent, germanium was absorbed over 98% at the conditions of mobile phase pH=1.5～2.5 and 1.30cm/min linear flow rate. The impurities Zn,Fe,Cu,Cd have no influence on germanium absorption and can be eluted almost completely by water.
