At different temperatures, indicators, pH, and other situations, exchange oscillopolarographic titration was used to detect phosphorus, silver, lead, thallium, cobalt, nickel, potassium bromate, potassium ferricyanide sodium tetraphenylborate, hydroxyquinoline. It also can be used in the determination of sulfate in extracted phosphoric acid, vitamin C, and trace mercury in industrial waste water. This method is high sensitive and selective. Further it can omit the separating steps, simplify the testing procedures, save analyte samples, and detect the very weak acids and alkalis. Phenomena are obvious and deviation is negligible.展开更多
文摘This paper reviews the development of exchange oscillopolarographic titration research, and focuses on its change in the past 20 years. At different temperatures, indicators, pH, and other situations, exchange oscillopolarographic titration was used to detect phosphorus, silver, lead, thallium, cobalt, nickel, potassium bromate, potassium ferricyanide sodium tetraphenylborate, hydroxyquinoline. It also can be used in the determination of sulfate in extracted phosphoric acid, vitamin C, and trace mercury in industrial waste water. This method is high sensitive and selective. Further it can omit the separating steps, simplify the testing procedures, save analyte samples, and detect the very weak acids and alkalis. Phenomena are obvious and deviation is negligible.
