磺酰胺萃取回收水中的汞(Ⅱ)

Recovery of Mercury(Ⅱ) in Aqueous Solution by Sulfonamides Extraction

研究了２－（十二烷基苯磺酰胺）噻唑和２－（十二烷基苯磺酰胺）苯并噻唑萃取汞（Ⅱ）的行为。研究表明，这两种萃取剂在一定的条件下，能有效萃取汞（Ⅱ），并采用斜率法探讨了它们对汞（Ⅱ）的萃取机理。

The extraction behaviors of mercury(Ⅱ) with the two synthesized 2 (dodecylbenzene sulfonamido) thiazole and 2 (dodecylbenzene sulfonamido) benzothiazole were studied. They can effectively extract mercury (Ⅱ) under certain conditions. The extraction mechanism of mercury (Ⅱ) by means of slope method is discussed.
