由于有机汞的毒害比无机汞大,环境保护中要求测知水中有机汞的含量。水中有机汞化合物的测定,目前多采用薄层分离原子吸收测定,或用有机溶剂抽提水中的有机汞化合物,抽出液用带有电子捕获鉴测器的气相色谱测定。操作手续繁复,且受设备条件的限制。近年梅崎芳美等利用强碱性介质和酸性介质还原气化水中的汞离子用原子吸收法分别测定总汞和无机汞含量,从总汞量扣除无机汞量简接地测知有机汞的含量。R.J.Baltisberger 则在过氯酸介质中还原汞测定无机汞含量,用过氧化氢加少量的锡预氧化后再用原子吸收测知
As organic mercury is more toxic than inorganic mercury, environmental protection requires the detection of organic mercury in water. Determination of organo-mercury compounds in water, the current use of thin-layer separation atomic absorption spectrometry, or organic solvent extraction of organic mercury compounds, the extraction liquid with electron capture detector gas chromatography. Complex procedures, and equipment constraints by the conditions. In recent years, Mei Misaki and other countries using strong alkaline medium and acidic medium to reduce the gasification of mercury in water by atomic absorption method were measured total mercury and inorganic mercury content, total mercury content deducted from the amount of inorganic mercury measured grounded organic mercury content. R.J. Baaltisberger mercury in perchlorate reduction of mercury in the determination of inorganic mercury content, with hydrogen peroxide plus a small amount of tin pre-oxidation and then detected by atomic absorption
