| Abstract: | This paper describes a method for the analysis of trace thorium by using N263 solvent extraction technique to separate the element from other elements like uranium, radium and rare earth in the envir on mental samples. Such influencing factors as extraction, reverse extraction, interfering ion, ect. were examined.The method was used for analysing soil, water, coal, plant samples collected in Shanghai. |
