| Abstract: | The applicability of 90Sr analysis in the contaminated sandy clay was studied by deposited balance method.The results indicated that relative error of adding standard samples was ≤12.4% and RSD of parallel sample was ≤10.8%.Results of actual sample in comparative analysis were reliable.The method could easily get rid of impurity and had steady recoveries for flow analysis of large quantities of sandy clay samples. |
