| 摘 要： | 研究了新型杯4]芳烃D对Pb2+,Cd2+离子的液-液萃取性质,并将其与自制的杯4]芳烃A及其衍生物B、C对Pb2+,Cd2+离子的液-液萃取性质进行了比较。结果表明,与化合物A~C相比,D对Pb2+萃取率最高,在实验条件下,可达到42.8%;测试的四种化合物对Cd2+离子的萃取效率均不佳,未经任何修饰的杯4]芳烃A的萃取效率最高,仅8.5%。推测对Cd2+的萃取为阳离子交换机理。

| Abstract: | Liquid-liquid extraction properties of new calixarene derivatives D to Pb~(2+) & Cd~(2+) were studied,and the comparison of the properties with the self-made calix4]arene A and its derivatives B,C were made.The results showed that compound D has the highest extracting rate up to 42.8% towards Pb~(2+) among A,B and C under the conditions of the experiment;and all rate of extraction of four tested compounds to Cd~(2+) were poor.Unmodified calix4]arene A,which extracting rate was the best one,reached only 8.5%.Cation interaction mechanism has been proposed. |
