Hg^(2+)-KI-罗丹明B配合物萃取分光光度法测定微量Hg^(2+)

Extractive Spectrophometric Determination of Trace Hg^(2+) by Complex Hg^(2+)-KI-Rhodomine B

本文研究结果表明，在磷酸介质中，HgI2-4与罗丹明B形成的紫色配合物可被三氯甲烷定量萃取。提出一个测定水中微量Hg2+的新的萃取分光光度法。

The result of the article shows that in the medium of phosphoric acid. the purple complex formed by HgI2-4-Rhodomine B Can quantitatively be extracted by trichloromethane.So a new extractive spectrophometric determination of trace mercury in water is suggested.
