冷原子吸收光谱法测定汞在各种水样中已广泛应用。水样中有机汞的分解方法,多年来一直使用在酸性条件下用氧化剂回流加热,这种操作比较复杂费时,近几年来国内外对直接加热分解方法研究较多,其中硫酸—高锰酸钾—过硫酸钾和硫酸—高锰酸钾直接加热法~1,已作为水样测定的试行方法,但该法要加热煮沸,有时甚至会出现爆跳现象,往往给操作者
Cold atomic absorption spectrometry has been widely used in a variety of water samples. The method of decomposition of organic mercury in water sample has been used for reflux heating with oxidant under acidic conditions for many years. This operation is complicated and time-consuming. In recent years, there are many studies on the direct heating and decomposition methods at home and abroad. Among them, sulfuric acid-potassium permanganate - Potassium persulfate and sulfuric acid - potassium permanganate direct heating method ~ 1, has been used as a water sample test method, but the law to heat boil, sometimes even popping phenomenon, often to the operator
