近年来,反相分配色层法有较快的发展。瑟克尔斯基(Секерский)等用磷酸三丁酯吸附在硅胶上作固定相,以硝酸淋洗分离Zr~(95)与Nb~(95);秦启宗等以磷酸三丁酯及二-(2-乙基己基)磷酸等为固定相分离铀与某些单个放射性同位素。
In recent years, the reversed-phase distribution of color method has a faster development. (Секерский) and other tributyl phosphate adsorbed on silica gel stationary phase, with nitric acid leaching separated Zr ~ (95) and Nb ~ (95); Qin Qizong and other tributyl phosphate and bis 2-ethylhexyl) phosphoric acid as the stationary phase to separate uranium from certain single radioisotopes.
