【摘要】 燃煤电厂排放的烟气中重金属有害污染物主要有汞、镉、铅、铬和砷等,其中汞是最容易挥发的重金属元素之一。本文重点介绍了冷原子吸收分光光度法、F732-VJ型冷原子吸收测汞仪的测试方法及精密度和准确度的测定,研究不同浓度还原剂硫化亚锡的测试效果,并对江阴某燃煤电厂烟气中汞含量进行测定。更多还原

【Abstract】 The harmful pollutants of heavy metals in the flue gas discharged from coal-fired power plants mainly include mercury, cadmium, lead, chromium and arsenic, among which mercury is one of the most volatile heavy metal elements. This paper mainly introduces the cold atomic absorption spectrophotometry, the test method of f732-vj cold atomic absorption mercury meter, the determination of density and accuracy, studies the test effect of different concentrations of reducing agent stannous sulfide, and determines the mercury content in the flue gas of a coal-fired power plant in Jiangyin.更多还原
