Study on the Cyclic Voltammetry Curve of Electrode in the Electrolytic Process of Seawater Pretreatment

Abstract:

The performance of the electrode is the core technology of the electrolytic process of seawater pretreatment, and has the decisive influence on the systematic technological process and water quality. In the initial stage of electrolytic technology being applied in seawater pretreatment, soluble anodes, which use the aluminum, ferrum or other metal elements as the main ingredient, are chosen for most cases. And this method can effectively reduce the turbidity of raw seawater and sludge density index (SDI). While applying a variety of methods, the proportion of electrolytic aluminum, ferrum and other metal elements in the water can be effectively controlled. And this can increase the ratio of hydrolysate, but will also introduce the composition of soluble electrode into the seawater inevitably. This study uses electrodes which contain a variety of precious metal (such as Ti, Ru, and Ir) oxide in the seawater pretreatment process, which is different from traditional chlor-alkali industry.
