A simple and rapid method for the simultaneous determination of 11 metals (As, Be, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, and Zn) in urine by inductively coupled argon plasma-atomic emission spectrometry is presented. Acidification of the urine was the only sample preparation required. Background correction was applied to ensure accuracy. Analytical calibration was based on matrix matching using a "simulated urine" solution. Detection limits in the low mg/L range and linearity over three orders of magnitude were obtained for all 11 metals. In the Occupational Health Laboratory, this procedure has been applied for routine screening of workers for occupational exposure to toxic metals.
本文介绍了一种通过电感耦合氩等离子体原子发射光谱法同时测定尿液中11种金属（砷、铍、镉、钴、铬、铜、汞、锰、镍、铅和锌）的简单快速方法。尿液酸化是唯一需要的样品制备步骤。采用背景校正以确保准确性。分析校准基于使用“模拟尿液”溶液的基体匹配。所有11种金属均获得了低mg/L范围内的检测限和三个数量级的线性度。在职业健康实验室中，该方法已应用于对工人进行职业性接触有毒金属的常规筛查。
