Abstract

A lower rim functionalised calixarene molecule 5,11,17,23-tetra-tert-butyl-25,27-bis(hydroxy)-26-(ethoxycarbonylmethoxy)-28-(diethyl carbamoyl-methoxy) calix[4]arene, which was originally developed for solid phase extraction of trace uranium from environmental and industrial waste water, is tested as a possible ionophore in ion selective electrodes (ISEs). PVC based membranes containing the calix[4]arene were used in experiments to test the characteristics and viability of these sensors. The electrodes gave more stable potential readings when used around neutral pH 5.5–8.5. Extraction experiments using the PVC membranes showed that the calix[4]arene complexed with the uranyl species end extracted it from the test solutions most effectively at around pH 7.0. The limit of detection for uranium species, around 1 ppm under normal conditions, was avoided by preconditioning the membranes at high pH. The effect of testing for uranium selectivity amongst a matrix of cations and anions in a simulated waste solution showed that interference was significant. As we are at the beginning of this research, suggestions for further work on these electrodes are made in light of recent reports of work in this field.

杯芳烃离子载体在聚氯乙烯基铀离子检测中的应用

一种下缘功能化杯芳烃分子5,11,17,23-四叔丁基-25,27-双（羟基）-26-（乙氧羰基甲氧基）-28-（二乙基氨基甲氧基）杯芳烃，最初是为从环境和工业废水中固相提取微量铀而开发的，在离子选择电极（ISEs）中作为一种可能的离子载体进行了测试。利用含有杯状[4]芳烃的聚氯乙烯基膜进行实验，以测试这些传感器的特性和可行性。当在中性pH值5.5-8.5附近使用时，电极提供了更稳定的电位读数。用PVC膜进行的萃取实验表明，在pH 7.0左右，杯状[4]芳烃与铀酰络合物端从测试溶液中萃取效果最好。通过在高ph下对膜进行预处理，可以避免在正常条件下约为1ppm的铀种检测极限。在模拟废液中对正阴离子基质中的铀选择性进行测试的影响表明，干扰是显著的。由于我们正处于这项研究的开始，因此根据该领域最近的工作报告，对这些电极的进一步工作提出了建议。
