对多氨羧基螯合树脂SL-401的性能进行了系统研究,该树脂的特点之一是吸附钴与镍有明显差别,能从大量钴中选择性地分离微量镍和铜。已成功地用于测定化学纯或分析纯钴盐中微量镍和铜。
The performance of polyamino carboxylate chelating resin SL-401 was systematically studied. One of the characteristics of this resin is that the adsorption of cobalt and nickel are obviously different, and can selectively separate trace amounts of nickel and copper from a large amount of cobalt. Has been successfully used to determine trace amounts of nickel and copper in chemically pure or pure cobalt salts.
