摘　　要：应用WGC-200型微分测汞仪,研究石化工业外排废水样品中汞的测定技术。将水样以适量的硫酸酸化,加高锰酸 钾使汞成为离子状态,再以氯化亚锡为还原剂,在酸性介质中测定汞,回收率为:95％-116％,最低检出限可达0.Apply WGC - 200 model differential to measure mercury instrument, Besides research petrochemical industry, queue up the measuration technology mercury in useless sample article. Will sample in with the acid of nitric acid of suitable quantity melt, Add potassium permanganate to make mercury become ion state, Is reducing agent again with chlorination inferior tin, In acid medium, survey mercury, collect rate is : 95%-116%, mininum jian can reach 0. 00001 tiny g/ milliliters.
