The method of stripping and separation of K(I) and Rb(I) with inorganic acid solution from 4-t-butyl-2(α-methylbenzy) Phenol(t-BAMBP) load organic phase was investigated.The effects of washing phase ratio,type of inorganic acid,concentration of nitric acid,phase ration of stripping,time and the extraction performance of regenerate t-BAMBP etc.on the stripping process were discussed,and processing condition was optimized.Under the condition,the stripping rate of rubidium reaches 95.48%.The regenerate t-BAMBP...
