据报导,指示剂离子电极已茜素 S、铬天青 S、铬黑 T、邻苯二酚紫、萘基偶氮8—羟基喹啉及8—羟基喹啉—5—磺酸根等多种。本文通过比较三种季铵盐和一种季磷盐研制了以碘化十六烷基三辛基铵为定域体,邻苯二甲酸二壬酯为增塑剂的 PVC 膜单电极,碳纤维复合电极,并联电极和串联电极,测试了它们的性能。试验表明并联电极的响应速度明显改善,串联电极能提高测量准确度。该电极不仅对两价的磺基水杨酸根 HSSA~(2-)有 It has been reported that the indicator ion electrode has alizarin S, chrome azure S, chrome black T, catechol violet, naphthylazo 8-hydroxyquinoline and 8-hydroxyquinoline-5-sulfonate and other . In this paper, by comparing three kinds of quaternary ammonium salt and a quaternary phosphonium salt developed cetyl trioctylammonium iodide as delocalization body, dinonyl phthalate plasticizer PVC membrane single electrode, carbon fiber Composite electrodes, shunt electrodes and series electrodes were tested for their performance. Experiments show that the response speed of parallel electrodes has been significantly improved, and the series electrodes can improve the measurement accuracy. The electrode is not only bivalent sulfosalicylate HSSA ~ (2-) have
