摘要
以吗啉和六氢吡啶修饰的四种对叔丁基杯[n]芳烃酰胺类衍生物(n=6,8)为萃取试剂,研究了它们对Na+,K+及部分过渡金属等十种金属离子的萃取作用.结果表明此类杯芳烃酰胺类衍生物对过渡金属离子有良好的选择性识别作用.其中,吗啉取代基修饰的杯[8]芳烃萃取效果最好.
The extracting properties of p-tert-butylcalix[ n] arene amide derivatives ( n = 6, 8) modified at the lower rim with morpholine or pyridine groups for Na^ +, K ^+ and some transition metal cations were studied with atomic absorption methods. The primary results showed that the calix[ 8] arene amide bearing morphine group has best extraction capabilities.
