Technology Study on Determination of Sr in Environmental Water Samples Using ICP-AES Method(In Chinese)

It is necessary to establish a rapid method for determination of Sr in order to accurately calculate chemical recovery in detemination of ~(90)Sr.Determination of Sr in environmental water samples by ICP-AES method was studied in the paper.In the optimum condition,detection limit of the method is 0.000 6 mg/ L,relative standard deviation is less than 3%,recoveries differ from 90.17% to 108.0%.The results show that the method can meet the need of determination of Sr in environmental water samples and apply to substract Sr backgroud content in radiochemical analysis for ~(90)Sr.
