磺酰胺类萃取剂对锌、镉的萃取性能

Research on Sulphonamide Extractants of Extraction With Zinc and Cadmium

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

This paper studies the extraction behaviors of zinc(Ⅱ) and cadmium(Ⅱ )with the two synthesized 2-(dodecalbenzenesulphonamido) thiazole and 2- (dode-calbenzenesulphonamido) - benzothiazole extractants and show s that they can effectively extract zinc(Ⅱ) and cadmium(Ⅱ) under certain conditions. Meanwhile,the extraction mechanism of zinc(Ⅱ) and cadmium( Ⅱ) by means of slope method is discussed.
