Used titanium electrode meshes ( Ti/RuO₂-IrO₂ electrodes ) from sodium hypochlorite generators typically possess considerable recycling value, primarily due to their precious metal coating.
These are not ordinary titanium meshes, but rather metal oxide-coated titanium anodes (MMO anodes). The anode surface is coated with an active coating containing precious metal oxides such as ruthenium (Ru) and iridium (Ir). This design allows them to operate stably in highly corrosive electrolytic environments. This article will help you unlock the recycling value of electrolytic cells in discarded sodium hypochlorite.
What do we recycle about sodium hypochlorite generators?
The recycling value of the electrode mesh depends primarily on the content and type of precious metals in its coating. Below is a comparison of different coating types and their core value:
Iridium Titanium Mesh / Ruthenium-Iridium Titanium Mesh
Core Value: Iridium (Ir). This is the most expensive type; metallic iridium can cost more than eight times that of gold (approximately several thousand yuan per gram).
Typical Coating Components: Primarily iridium oxide, or a mixture of iridium and ruthenium oxides.
Application Scenarios:** Commonly used in high-requirement fields such as the chlor-alkali industry (producing caustic soda and chlorine), and water electrolysis for hydrogen production.
Ruthenium-plated Mesh / Ruthenium-coated Titanium Mesh
Core Value: Ruthenium (Ru).
Typical Coating Components: Primarily ruthenium oxide.
Application Scenarios: Widely used in the chlor-alkali industry, electroplating, and wastewater treatment. Some sodium hypochlorite generators also use this type of coating.
Other Precious Metal Coatings (e.g., Platinum Pt)
Core Value: The corresponding precious metal (e.g., platinum).
Typical Coating Components: Depends on the design.
Application Scenarios: Specific corrosion-resistant or catalytic environments.
Recycling Value Reference: High. Depends on the specific type and content of the precious metal.
How to Evaluate and Quote for Titanium Electrode Mesh?
Many customers ask about the price of scrap titanium electrodes. We typically provide a comprehensive quote based on a combination of factors, including the weight of the electrode mesh, current precious metal market prices, actual coating content detected during testing, recycling process costs, and global market supply and demand.
