摘要
Abstract
In order to achieve continuous monitoring of 90 Sr in aqueous solution ,90 Sr was firstly separated selectively and enriched by SuperLig ® 620 solid phase extraction beads ,which was then measured in‐situ using plastic scintillator .The influences of 90Sr activity on two‐phase equilibrium were studied and the results show that the concentra‐tion in aqueous solution is directly proportional to that captured on the column in 0.2 mg/L Sr‐0.01 mol/L HNO3 medium .So the concentration of 90 Sr in aqueous solu‐tion can be analyzed by detecting 90 Sr on the column .The detection efficiency and mini‐mum detectable activity are 21.3% and 2.6 Bq/L ,respectively .The concentration of 90 Sr in low level radioactive waste water was analyzed using the above method and the analytical error is lower than 20% .关键词
