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。
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.
