Electrodialysis is a type of membrane separation technology,It is under the action of DC electric field,Using potential difference as the driving force,Utilizing the selectivity of ion exchange membranes,Separate and remove useless salts in electrolytes from solutions,To achieve product concentration、Purpose of refining or purifying。
Titanium electrode is one of the main components of electrodialyzer,It directly affects the normal operation and desalination effect of the electrodialyzer。
In the production process of electrodialysis,The resistance to the reaction current is divided by the resistance of the membrane stack 、solution resistance ,Also comes from the polarization resistance of the electrode reaction 。That is to say ,Choose a material with a smaller oxygen evolution overpotential as the anode，A larger reaction current can be obtained。
The ruthenium titanium anode produced by Zhongrui Guoneng has the advantage of small oxygen evolution potential.，A larger reaction current can be obtained；Solid solution of multi-component noble metal oxides formed during co-oxidation during heat treatment，Gives titanium anodes superior corrosion resistance；Pretreatment from titanium matrix、Coating liquid preparation、Coating application method、Optimize the production process of titanium anodes in terms of sintering process and other aspects，Give titanium anodes good chemical and electrochemical stability and long service life。
At present, electrodialysis technology has a wide range of applications，For example, water desalination and desalination、Seawater concentration, salt production, refined dairy products、Juice deacidification and purification、Preparation of chemical products, etc.；Can also be used for food，Preparation of pure water in light industry and other industries；electronic、Pretreatment for producing high-purity water in pharmaceutical and other industries；
in electronics、medicine、Chemical industry、Thermal power generation、Food and other industries，Electrodialysis technology can be used for water treatment；
Electrodialysis can also be used in wastewater、Waste liquid treatment and precious metal recovery，For example, recovering nickel from electroplating waste liquid。
