摘要
目的：为开展职业病体检、人群本底水平调查等大批量尿样中汞的检测提供简单、省时、可靠的检验方法。方法：采用原子荧光法对经过水浴消解的尿样进行汞含量的检测。结果：本法最低检出限0.0016μg/L,测定范围在0~100μg/L有良好的线性关系,r=0.9994;精密度试验2份不同尿样的RSD分别为2.31%和1.12%。回收率试验2份尿样分别加入低、高两种不同浓度的标准其回收率分别为97.0%、98.2%、98.6%、98.9%。结论：水浴消解-原子荧光光谱法是快速、简便、可靠的测定尿汞的检测方法。
Objective：To offer a simple and time-saving and reliable analysis method for investigation of the mercury in the urine in order to investigate occupational diseases and baseline level in healthy population.Methods： Applying digestion in the water bath coupled with atom fluorescence spectrometry to determine the mercury in the urine.Results： The detective limits 0.0016 μ g/L,good linearity in the range from 0 μg/L to 100 μg/L,r=0.9994;the RSD（%） of two urine samples ： 2.31%,1.12%,the recovery rate（%）：97.0%,98.2%,98.6%,98.9%.Conclusion： The method is considered to be a quick,simple and reliable for measuring large amount of samples.
