It is well known that 90Sr is one of the most important radionuclides present in nuclear wastes and its removal can reduce storage risks caused by its long haft-life(28.5 years)[1]. A lots of work has studied the extraction of strontium using macrocyclic crown ethers as extractants from aqueous solutions into an organic phase[2~4]. In the present study,the extraction of microamounts of Sr2+ from nitric acid solutions by dicyclohexyl-18-crown-6(DCH18C6)as extractant into 1,1,2,2-tetrachloroethane has been investigated. The extraction experiments in the two-phase water-HNO3
