| Abstract: | A method for the determination of 40K in environmental water samples by inductively coupled plasmaoptical emission spectrometry (ICP-OES) was established.The detection limit for this method is 0.001 Bq/L with relative standard deviation of less than 1.5％ and relative error of less than 4.0％.The recoveries of standard addition is 94.1％-105.5％.The method is a promising candidate for the analysis of 40K in water samples due to good linear correlation,low detection limits,high precision,and little interferences. |
