无机离子交换剂具有耐高温、抗辐射及较高的交换容量等优点,在原子能研究领域中,日益受到重视。Kraus等报道四价金属的钨酸盐和磷酸盐具有显著的离子交换性质。Gal等在磷酸锆柱上,用磷酸三丁酯-硝酸作淋洗剂,分离了毫克量的铀与裂变产物(含有铈~(144)、钇~(90)等稀土元素)。对钨酸锆的研究较少,且多用于碱金属的分离。william
Inorganic ion exchangers have the advantages of high temperature resistance, radiation resistance and high exchange capacity, etc., and are gaining more and more attention in the field of atomic energy research. Kraus et al. Reported that tetravalent metal tungstates and phosphates have significant ion exchange properties. Gal and other zirconium phosphate columns, the use of tributyl phosphate - nitric acid as eluent, uranium and fission products of milligram separation (containing cerium ~ (144), yttrium ~ (90) and other rare earth elements). There is less research on zirconium tungstate and more for the separation of alkali metals. william
