摘要： 基于经典的离子交换剂如季铵盐、季鏻盐和邻菲罗啉配合物等的溶剂聚合膜电极对阴离子呈现出Hofmeister选择性序列.目前,研究反Hofmeister行为的阴离子选择性电极已成为化学传感器研究领域的重要研究方向之一.该类电极通常以金属卟啉及其衍生物、维生素B12衍生物和金属酞菁及其衍生物等作为载体,研制出了SCN-,NO2-,Cl-和I-等选择性电极.采用席夫碱金属配合物及金属汞.

Abstract: In this paper, anion-selective electrode based on bis-salicylaidehydc-diaminodipropylamine cobalt (Ⅱ) metallic complex [Co(Ⅱ)-BSADDPA] as the neutral carrier is reported. The sensor exhibits a u-nique selectivity and high sensitivity toward salicylate ion, which displays an anti-Hofmeister selectivity pattern. It gives a linear response in the concentration range 3. 0× 10-6-1. 0× 10-1mol/Land a response slope of -66. 8 mV/dec in buffer solutions of pH 4. 0. The response mechanism is discussed in view of the UVspectroscopy technique. The electrode can be applied to medicine analysis and the result is in fair agreement with the result given by precipitation method.

Key words: Solvent polymeric membrane, Neutral carrier, Salicylate ion, Bis-salicylaldehyde-diamin- odipropylaminecobalt(I)
