Abstract: A method for the determination of 40K in environmental water samples by inductively coupled plasma-optical 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.

Key words: ICP-OES, environmental water samples, 40K
