磺酰胺萃取回收水中的铅

Recovery of Lead(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 )苯并噻唑萃取铅(Ⅱ )的行为。研究表明 ,这两种萃取剂在一定的条件下 ,能有效萃取铅 (Ⅱ ) ,并采用斜率法探讨了它们对铅 (Ⅱ )的萃取机理。

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