摘要
[目的]验证原子荧光法测定硒的检出限和精密度的准确性。[方法]运用双道原子荧光光度计AFS－9730测定硒的检出限和精密度，检验其是否满足环境保护部新颁布的《水质汞、砷、硒、铋和锑的测定原子荧光法》（HJ 694—2014）对检出限和精密度的要求。[结果]原子分光光度计测定硒的检出限为0．0052μg／L，相对标准偏差为0．78％。[结论]原子分光光度计测定硒的检出限和精密度满足环境保护部新颁布的《水质汞、砷、硒、铋和锑的测定原子荧光法》（HJ 694—2014）的要求。
Abstract
Objective] To research the detection limit and precision of selenium detected by atomic fluorescence spectrometry.[Method] Double channel atomic fluorescence spectrometry AFS-9730 was used to detect the detection limit and precision of selenium.We researched whether the detection limit and precision met the requirements of Water Quality-Determination of Mercury, Arsenic, Selenium, Bismuth and An-timony-Atomic Fluorescence Spectrometry (HJ694-2014).[Result] The detection limit of selenium was 0.005 2 ug/L by atomic fluorescence spectrometry, with the relative standard deviation being 0.78%.[Conclusion] Detecting the precision and detection limit by atomic fluores-cence spectrometry meets the requirements of Water Quality-Determination of Mercury, Arsenic, Selenium, Bismuth and Antimony-Atomic Fluo-rescence Spectrometry (HJ694-2014).
