【摘要】 主要探讨应用AFS-830型双道原子荧光光度计,在饮用水监测中同时测定水中砷、汞的方法和技术。此法是在硝酸介质,以硼氢化钠作还原剂,进行原子化,被测元素原子激发出荧光强度值在一定范围内与被测元素的浓度成正比。砷与汞的检出限分别为0.061 8和0.0158 ug/L。更多还原

【Abstract】 This article mainly discusses the method and technology of determining Arsenic,Mercury in drinking water simultaneously by use the AFS—830dual channel atomic fluorescence photometers.In nitric acid medium,the analyzed elements are atomized with the reducer of sodium borohydride,the excited fluorescence intensity is proportional to the elementary concentration within limits.Detecting limits of the Arsenic,Mercury are 0.061 8 and 0.015 8 ug.L-1 respectively.更多还原
