Application
Water treatment
Iridium tantalum coated titanium anodes find application in water treatment, where the anodes works for processes like electro-oxidation and electrochemical disinfection of municipal wastewater and industrial effluents. The anodes also exhibit outstanding electrocatalytic activity for oxygen evolution from water, generating reactive oxidants to degrade organic pollutants and inactivate disease-causing pathogens.
Electrocatalytic Oxidation
Used for wastewater treatment, utilizing specific chemical reactions to effectively remove pollutants, disinfect water, and oxidize organic compounds (COD), ammonia nitrogen, decolorization, etc. These anodes play a crucial role in improving water quality and achieving environmental sustainability.
Chlor-alkali industry
The chlor-alkali industry utilizes iridium tantalum coated titanium extensively in the electrolysis of brine for chlorine and caustic soda production. The electrodes withstand the highly corrosive brine environment while also electrolyzing salt efficiently over prolonged production runs. The dimensional stability of the titanium substrate coupled with the electrocatalytic activity of the iridium tantalum coating enables consistent and reliable performance.
Electroplating
For metal electroplating processes, like chromium plating, and other electroplating applications including nickel, copper, tin, zinc, and precious metals, iridium tantalum coated titanium anodes provide inert, non-consumable anodes necessary for uniform metal deposition onto cathodic workpieces. The anodes eliminate metal contamination from anode dissolution observed with consumable metal anodes.
Electrochemical synthesis
In the electrochemical synthesis of organic compounds and specialty chemicals, iridium tantalum coated titanium anodes withstands aggressive organic intermediates/reagents while facilitating selective electrochemical oxidation reactions at its surface. In case applications, like electrochemical fluorination and electrophilic aromatic substitution, iridium tantalum coated titanium electrodes can produce useful fluorinated and chlorinated aromatic compounds.
Cathodic protection
Additionally, iridium tantalum coated titanium anode is used as an inert auxiliary anode material in cathodic protection systems for corrosion prevention in pipelines, storage tanks, marine structures, and other metal infrastructure.
