汞是地球化学找矿的重要指示元素之一,在地壳中的含量仅有7×10~(-16)%.为满足找矿的需要,近年来采用了多种检测手段,提出了一些高灵敏度的测试方法.其中冷原子吸收法应用较广,但一般将样品分解之后再转入反应瓶测定,手续繁琐,易沾污.本文从生产实际出发,为提高经济效益,特制了一种反应瓶,将待测样品转入瓶中,用稀王水水浴分解,于不分离矿物残渣的条件 Mercury is one of the most important elements in geochemical prospecting, and its content is only 7 × 10 ~ (-16)% in the crust. In order to meet the need of prospecting, a number of detection methods have been adopted in recent years, Sensitivity of the test method, which is widely used in cold atomic absorption method, but the general decomposition of the sample into the reaction flask after the determination, tedious procedures, easy to stain.In this paper, starting from the actual production, in order to improve economic efficiency, a special reaction Bottle, the test sample into the bottle, with dilute Wang water bath decomposition, in the condition of not separating the mineral residue
