本文研究了含有叔胺(N_(235))的溶剂浸渍树脂,试验发现,它们吸附金属氯络阴离子的次序类似于溶剂萃取。然而,树脂的吸附容量和动力学却与载体的结构和树脂内叔胺的含量有关。试验了从镍阳极液中净化除去三价铁离子。结果表明除铁效果是令人满意的。连续试验发现。在使用过程中树脂内叔胺的损失是极少的。
In this paper, we studied the impregnation of resins with solvents containing tertiary amines (N 235) and found that the order of adsorption of metal chloride anions is similar to that of solvent extraction. However, the adsorption capacity and kinetics of the resin are related to the structure of the support and the content of tertiary amine in the resin. Trivalent ferric ions were purified from the nickel anolyte. The results show that iron removal is satisfactory. Continuous test found. The loss of tertiary amine in the resin during use is minimal.
