用络合水介法合成了羟氧化■锑(V)无机离子交换剂,报导了它的组成和离子交换性质,测定了Na~+、K~+离子的分配系数,并用柱式操作达到Na~+、K~+离子的有效分离。 合成无机离子交换剂由于耐高温和抗放射作用,以及对某些元素的特殊选择性,因而广泛用于核工业、湿法冶金工业、纯物质制备,从工业废水中回收有用物质等部门。 锑型无机离子交换剂对碱金属和碱土金属有高选择性。本工作用络合水解法合成了羟氧化■锑(V)无机离子交换剂,并用其进行了K~+、Na~+混合离子的柱式分离。
Antimony (V) inorganic ion exchangers were synthesized by complexation mediated method. Its composition and ion exchange properties were reported. The partition coefficients of Na ~ + and K ~ + ions were determined and the column operation was used to obtain Na ~ +, K ~ + ion effective separation. Synthetic inorganic ion exchangers are widely used in the nuclear industry, hydrometallurgy industry, preparation of pure substances and the recovery of useful substances from industrial wastewater because of their high temperature resistance and radiation resistance and their special selectivity to certain elements. Antimony type inorganic ion exchangers have high selectivity to alkali metals and alkaline earth metals. In this work, hydroxylated antimony (V) inorganic ion exchangers were synthesized by complex hydrolysis method and were used for the column separation of mixed ions of K ~ + and Na ~ +.
