目前使用的有机离子交换树脂缺乏耐高温、耐强放射性辐射的性能,因而它们在许多领域中的应用受到限制。而无机物一般均具有这些性能,故对其研究发展迅速。现在已合成了大量的无机离子交换剂,可以按其结构进行分类,其中四价金属的不溶性酸式盐研究得最深入,而磷酸锆(以下均用ZrP来表示)最具有代表性,研究也比较成熟。
The currently used organic ion exchange resins lack the properties of high temperature resistance and strong radiation resistance, and thus their use in many fields is limited. However, inorganic materials generally have these properties, so their research is developing rapidly. Now a large number of inorganic ion exchangers have been synthesized, which can be classified according to their structure. Among them, insoluble salts of quaternary metals are the most studied, while zirconium phosphate (all expressed as ZrP) is the most representative. More mature.
