微波消解-原子荧光法测定尿中汞、砷探讨

Microwave Digestion-Atomic Fluorescence Spectrometry in Urine Mercury,Arsenic Study

[目的]建立一种梯度升压微波消解样品,氢化物发生原子荧光光度测定尿样中的汞砷的方法。[方法]2009年,在某厂体验中整群采集职工尿样。研究了消化液、灯电流、原子化器高度等因素对测定的影响。[结果]在优化实验条件下,尿样中的汞的回收率为92.3%-96.5%,砷的回收率为94.1%-103.6%。[结论]该法具有操作简便、快速、准确、灵敏、重复性好等优点。

[Objective]To establish a gradient step microwave digestion hydride generation atomic fluorescence spectrophotometric determination of mercury in urine arsenic.[Methods]In 2009,experience in the factory workers collected urine cluster.Of the digestive juice,lamp current,atomizer height on the determination of the optimized experimental conditions.[Results]The recovery of mercury in urine was 92.3%-96.5%,the recovery of arsenic was 94.1%-103.6%.[Conclusion]The method is simple,rapid,accurate,sensitive,reproducible and so on.
