Method Validation of Determination of Mercury in Groundwater by Atomic Fluorescence Spectrometry
According to HJ 168-2020 Technical guideline for the development of environmental monitoring analytical method stangards,the method detection limit,the lower limit of detectionr,precision and accuracy of mercury in the environmental standard HJ 694-2014 Water Quality-Determination of Mercury Arsenic,Selenium,Bismuth and Antimony-Atomic Fluorescence Spectrometry were verified.In this article,2.5 times and 5 times of the detection limit of the method were selected for seven parallel determinations.The result showed that the detection limit was 0.02μg/L,the lower limit of detection was 0.08μg/L,meeting the standard requirements.The relative standard deviation of precision was 0.41%～4.5%,and the relative standard deviation of accuracy was 0.26%～7.9%,both of which met the quality control requirements of HJ 164-2020(Technical specifications for environmental monitoring of groundwater).
