| Abstract: | PbO 2 can be used as electrode substance and Pt can be used as based material. The constant voltage volt ampere method was used to determine the value of current. The PbO 2 electrode can be used as work electrode in three electrode system. A method of raising volt to refresh the surface by bubbling was used to avoiding the surface being polluted. Such determined COD values were reliability and reproducibility well. So the method had good utilization in COD determination. |
