| Abstract: | This paper determined the value of current by the constant voltage volt-ampere w ith the new PbO 2 electrode as working electrode. We raised volt to re fresh the surface by bubbling, avoided the surface polluted, the determination o f the COD values of sample solutions of standard glucose and potassium biphthal ate recurrencely proves that the method is efficient. |
