摘要
以新型PbO2 电极作为工作电极组成三电极工作系统 .以恒电位伏安法的原理测定电流值 ,并通过增大电位气泡更新法对电极再生 ,来阻止电极表面被污染 ,保证了测量的重现性 .通过对葡萄糖标准溶液与邻苯二甲酸氢钾溶液COD值的测定 。
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.
