An ion-selective electrode of improved performance, particularly in mixed solvent systems, for example in analysis of ionic surfactants, consists of a solid support (1), preferably spectrographically pure graphite, on which is deposited a polyvinylchloride membrane (5) containing a minor proportion of an electroactive substance.
一种性能更好的离子选择电极,特别是在混合溶剂系统中,例如在离子表面活性剂的分析中,由一个固体支架(1)(最好是光谱纯石墨)组成,在其上沉积了一层含有少量电活性物质的聚氯乙烯膜(5)。
