摘要
采用原子荧光光谱法测定汞接触者尿样中汞的含量,并将本方法与冷原子吸收光谱法进行对比.结果表明,本法的最低检出限为0.025ng,测定范围为0～10.0μg/L,相对标准偏差为1.2%～4.3%,加标回收率为95.1%～101.7%.两种不同方法比对的相对误差小于10%.该方法具有操作简单、实用、快速、准确、灵敏度高、重复性好等优点.
The atomic fluorescence spectrophotometry method is used to measure the mercury consistency in urine,this method of lowest detection limits is 0.025 ng;the measurement scope is 0~10.0 μg/L;opposite standard deviation is 1.2%~4.3%;added standard recovery rate is 95.1%~101.7%.the opposite error of the two different methods is less than 10%.The methods is simply,practical,fast,accurate and repeatitive.
