摘要
本文合成了一种层状结构的聚磷酸铝,通过对物理——化学性能的测试表明它是一种离子交换容量大(7.27mmol/g),热和化学性能稳定的阳离子交换剂.对 K^+、NH_4^+等具有较高的选择性.
An aluminium polyphosphate with layered structure has been synthesized.The investigation on physicochemical property showed tbat it is a cation exchanger with high ion exchange capacity (7.27mmol/g),excellent thermal and chemical stabilities,and also high selectivity for K^+ and NH_4^+.
