摘要
Abstract
The influence of parameters (acidity,flow rate and amount)of cationic resin elu-tion,Sr resin leaching and elution were optimized by ortho-experiment.Combined with the enrichment of cationic resin,the separation of Sr specific resin and the measurement of α/βinstrument,a rapid analysis method of 90 Sr was established in environmental water.The chemical recoveries are over 95% when the method was used to actual water,indicating that this method is simple,short and efficiency,can provide stable chemical recovery,is suitable for enrichment and separation of 90 Sr in environmental water.When the Sr specific resin col-umn was used in environmental water after 10 times,the chemical recovery rate of Sr is still higher than 90%.The resin has high stability.关键词
