【摘要】 检测涂料中的砷、汞含量目前还没有相关的标准和方法。采用原子荧光法测定涂料中的砷和汞,在酸性介质中加入硼氢化钾溶液,使三价砷形成砷化氢气体,使二价汞还原成元素汞,具有谱线简单、灵敏度高、检出限低的优点,适用于砷汞元素的同时分析。更多还原

【Abstract】 Arsenic and mercury in paint was determined by atomic fluorescence. Potassium borohydrate was added into acid medium solution, trivalent arsenic form arsine gas, and Hg2+ was reduced to element mercury. This method had some advantages of simple lines, high sensibility and low detection limit, and was suitable for the determination of arsenic and mercury at same time.更多还原
