1967年Pedersen发表了大环聚醚的合成及性能的研究报告,1972年Rechnitz制成了第一支冠醚载体液膜电极,近年来有关以PVC膜为基体的不同王冠化合物电极的研究工作陆续有所发表,有些电极已有商品出售。但是,对王冠化合物PVC膜电极对金属离子响应的基本规律以及增塑剂的影响的研究仍较缺乏。本文采用电位法,选择了七种单环冠醚、一种桥联式双冠醚和一种开链酰胺型类冠
In 1967, Pedersen published a report on the synthesis and properties of macrocyclic polyethers. In 1972, Rechnitz made the first crown ether carrier liquid membrane electrode. In recent years, the research on different crown compound electrodes based on PVC membrane has been carried out Some published, some electrodes have been sold. However, there is still a lack of research on the basic rules of the response of the crown compound PVC membrane electrode to metal ions and the influence of plasticizer. In this paper, the potential method, the selection of seven kinds of single-ring crown ether, a bridged double-crown ether and a kind of open-chain amide crown
