How Dimensionally Stable Anodes Used for Electrochemical Wastewater Treatment? Dimensionally stable anodes (DSAs) have been investigated in electrochemical wastewater treatment. They typically consist of mixed metal oxide coatings on valve metal substrates. The functionality and selectivity of these electrodes are highly dependant on their physical structure and composition. These anodes conventionally use titanium as the substrate with either IrO2 or RuO2 as the electrocatalyst and TiO2, Ta2O5, ZrO2, or SnO2 as the stabilizer that

Why Titanium is Used as the Substrate of Dimensionally Stable Anodes? Titanium is commonly used as the substrate material for dimensionally stable anodes because it is not easily dissolved under anodic polarization in aqueous environments. The stability of titanium can be attributed to the compact oxide film that forms on its surface. This film forms naturally in the air, but forms more rapidly when the metal is polarized to an anodic potential in an aqueous electrolyte. Using titanium as the substrate for a DSA increases the

What is Electrochemical Water Disinfection? Electrochemical water disinfection can be defined as the elimination of microorganisms from a water sample using the passage of electrical current through that sample. Here the electrode materials are very important because upon application of the electrical current electrochemical reactions occur at the surface of the electrodes. At the cathode, hydrogen gas is produced, and at the anode, oxygen gas is produced along with oxidizing compounds that can include ozone, free chlorine, peroxid

Titanium Anode Basket for Nickel Copper Zinc Plating Titanium anode basket is significantly applied in nickel, copper, and zinc plating. The anode baskets are mainly cubic containers whose forward and rear walls consist of 0. 8-1. 0 mm thick expanded metal of various mesh sizes. The cross-section of the basket hooks must be so dimensioned that the current density does not exceed 1 amp. /mm2. In general, the basket hooks are manufactured of bars in square or flat cross-sections. They shall rest with one edge on the anode bus with po
