近十多年来,无机离子交换剂以其许多突出的优点,如耐电离辐射、耐高温、对某些放射性离子的高度选择吸着性、天然无机离子交换剂价廉物丰和合成无机离子交换剂制作比较容易等,而日益广泛地用于处理放射性废水。在这方面研究和应用最多的有粘土矿和沸石,其次是多价金属的氧化物或氢氧化物;对多价金属的不溶盐如磷酸锆等研究得较多,在大规模使用上还不多见。
For more than a decade, inorganic ion exchangers have attracted many outstanding advantages such as ionizing radiation resistance, high temperature resistance, highly selective sorption of certain radioactive ions, inexpensive natural inorganic ion exchangers, and synthetic inorganic ion exchange Agents are relatively easy to make, and are increasingly used to treat radioactive waste water. In this regard, the most studied and applied are clay minerals and zeolites, followed by polyvalent metal oxides or hydroxides; insoluble salts of polyvalent metals such as zirconium phosphate have been more studied in the large-scale use of not More common.
