摘要
Abstract
The performance of EmporeTM Strontium Rad Disk produced by 3M Corporation for the separation of strontium in aqueous solution was studied elaborately.The influences of sample acidity,volume and flow rate on strontium uptake efficiency were studied and maxi-mum strontium capacity was determined.The adsorption behavior of 137 Cs and 99 Tc on the disk was investigated as well as the elution method of strontium and counting method of 90 Sr on the disk.Based on the results,an analysis procedure of 90 Sr in environmental water sam-ple using SPE disks was presented.The minimum detectable activity is 0.033 Bq/L with a sample volume of 1 L and a detection time of 1 h.Finally,some 90 Sr spiked environmental water samples were determined to testify the procedure.关键词
