The Main Application Of “Dimensionally Stable Anodes” (DSA)

″Dimensionally stable anodes″ (DSA) is widely used in the area of wastewater treatment, electrolysis, and electroplating. The electrode has an important function in the electrochemical reaction, which has a great influence on the reaction speed and reaction mechanism. Meanwhile, electrode material has an important influence on many parameters, like momentum point during the electrochemical reaction. DSA plate, which has a long lifespan and no secondary pollution, can replace anode plate, which has big volume and heavy weight. It has other properties, like easy to process many shapes, higher catalytic property, and reusing substrate material.

DSA has been widely developed in the process of high-concentration and refractory salinity wastewater in recent years. Electrochemical oxidation technology is adopted in treating wastewater, which can change the nature and structure of organic pollutants. It’s one of the important fields for environmental protection’s development because it’s easy management operations, stable quality of output water, well decolorization effect, small usage of the land, and strong biodegradability.

DSA is also widely used in electrolysis. Use DSA as the anode, the insoluble anode plays the role of location and basal during electrolysis. DSA is an insoluble anode, what base martial is stainless steel, admire, and so on. Catalytic noble metal oxides are covered base martial. The electric field of the electrode interface has a great influence on the reaction speed because of the electrocatalysis of noble metal oxides. DSA has high energy conversion efficiency because it can get lower overpotential as an insoluble anode.

DSA covered noble metal oxides, in the production of electrolytic copper foil. Oxygen has low overpotential, long life span, and non-pollution. Comparing to a normal Pb-Ag anode, it can decrease cell voltage by more than 1.0V and save energy.

DSA’s technology of electrochemical reaction is mature as an insoluble anode. Currently, the insoluble anode is most extensively used most extensively in the Chlor-alkali industry. Make chlorine and caustic by electrolysis of salt liquor. Chlorine evolution is the main reaction at the positive pole, meanwhile, the secondary reaction is oxygen evolution. Chlorine evolution potential can be significantly reduced by DSA, and bubbles of chlorine can digress easily.
