摘要: 建立了利用电感耦合等离子体发射光谱仪(ICP-OES)测定环境水样中钾-40的方法。此方法标准工作曲线线性关系良好,检出限为0.001 Bq/L,相对标准偏差小于1.5%,相对误差小于4.0%,加标回收率在94.1%~105.5%之间,具有前处理简单、检出限低、精密度和准确度高、干扰小等优点,值得推广应用。

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
