测定微量汞 ,测汞仪具有快速、灵敏度高等特点。但一般实验室用单波长二硫腙分光光度法[1] ,二硫腙与Ｈｇ(Ⅱ )离子生成橙色络合物 ,反应非常灵敏 ,且络合物能被氯仿完全萃取。但二硫腙的氯仿溶液为绿色 ,试液中含有两种有色成分 ,它们的吸收峰又部分重叠 ,随着试液中Ｈｇ(Ⅱ )
Determination of trace mercury, mercury detector with a fast, high sensitivity and so on. However, in general laboratory with single-wavelength dithizone spectrophotometry [1], dithizone and Hg (II) ion generated orange complex, the reaction is very sensitive, and the complex can be fully extracted by chloroform. However, the chloroform solution of dithizone is green, the test solution contains two kinds of colored components, and their absorption peaks are partially overlapped. As the test solution Hg (II)
