直接测汞仪测定尿中总汞

Total mercury in urine determined by direct mercury analyzer

摘要:
目的建立以直接测汞仪测定尿汞的方法。
方法利用DMA80型直接测汞仪对尿样进行分析测定。
结果该方法在尿汞为1.0~200.0 ng水平时具有良好的线性关系，该方法检出限为0.4 μg/L，样品测定精密度为0.38%~1.68%，回收率为92.6%~96.9%。
结论该方法可以作为尿中总汞的日常检测方法。

Abstract:
ObjectiveTo establish a direct determination method for urine mercury
MethodsDMA80 Direct Mercury Analyzer was applied in determination of the total mercury in urine.
ResultsThe method showed a good linear relationship within the concentration range of 1.0-200.0 ng.The detection limit of this method was 0.4 μg/L, with the precision between 0.38% and 1.68%.The recovery rate was between 92.6% and 96.9%.
ConclusionThe method can be used as a conventional method in determination of the total mercury in urine.
