【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。更多还原

【Abstract】 Liquid-liquid extraction properties of new calixarene derivatives D to Pb²⁺ & Cd²⁺ were studied,and the comparison of the properties with the self-made calix[4]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 Pb²⁺ among A,B and C under the conditions of the experiment;and all rate of extraction of four tested compounds to Cd²⁺ were poor.Unmodified calix[4]arene A,which extracting rate was the best one,reached only 8.5%.Cation interaction mechanism has been proposed.更多还原
