【摘要】 <正> 关于PVC膜阴离子选择电极性能的优劣,除了和离子交换定域体(大阳离子)的结构有关外,还要取决于阴离子本身的结构,实验证明,在前者确定时,结构特性类似的阴离子对电极的响应特性也相近,这就意味着阴离子PVC膜电极的响应机理是雷同的,此为通用电活性物质提供了依据。本实验室还证明了石墨碳棒可作为良更多还原

【Abstract】 The universal electrode for several anions is suggested and proved experimentally in this paper.The Seven coated carbon PVC matrix membrane universal electrodes for several anions have been prepared with triheptyldodacylammonium, ethyl violet, night blue, butylrhodamine B, victory blue, janus green and cyanine dye No 13 respectively. Their response charecteristics for Ⅰ^-, ClO₄^-, picrate, SCN^-, InBr₄^-, ReO₄^-, IO₄^- and BF₄^- in proper order are studied and obtained good results except the janus green electrode. The universal electrode has two meanings. 1)An identical electrode can be universal to each other for several anions whose structural characteristics are similar; 2) The electrodes prepared in the same way can be used as alone or special electrode for one of the sevral anions.更多还原
