新型磺酰胺萃取剂对镍离子的萃取性能

Extraction Behaviors of Novel Sulfonamide Extractants for Ni^(2+)

合成了一种新型萃取剂 ,2 -十二烷基苯磺酰胺喹啉 (萃取剂Ⅰ ) .研究了它和 2 -十二烷基苯磺酰胺噻唑(萃取剂Ⅱ )的萃取性能 ,研究表明 ,这两种萃取剂在一定的条件下 ,能有效地萃取Ni2 + 离子 .同时采用斜率法探讨了它们对Ni2 + 离子的萃取机理 .

dodecylbenzene-sulfonamido quinoline was synthesized.Its extraction behaviors for Ni 2+,together with that of 2-dodecylbenzene-sulfonamido thiazole were studied.It is shown that they can effectively extract Ni 2+ under certain conditions and the extraction mechanism for Ni 2+ by means of slope method was discussed.
