摘要: The electrochemical oxidation of tetraphenylborate ions was investigated by using silicone rubber based graphite electrode. An indirect voltammetric method elaborated for the determination potassium and caesium. A is also given with sodium amperometric end-point indication. latter more accurate. relative standard deviation ± 0.85%.
