Unveiling Applications of Boron Doped Diamond BDD Electrode for Wastewater Treatment
We discussed about typical applications of boron doped diamond electrode before, in this section, we discuss details about electrochemical application of boron doped diamond BDD electrode for wastewater treatment, we will discuss about the mechanism, princles, and methods to accomplish complete removal of organic compounds:
Why Choose Boron Doped Diamond BDD Electrode for Wastewater Treatment
Boron doped diamond BDD electrode is an excellent electrode material used in electrochemical water treatment, wastewater remediation and disinfection via boron doped diamond electrode are proven to be efficient and environmental friendly, via various research, testing, treatability assessment in electrochemical advanced oxidation processes (EAOPs).
How Boron Doped Diamond BDD Electrode Functions for Wastewater Treatment ?
Check the schematic diagram within the section below, it explains direct and indirect oxidation reactions within the advancd oxidation processes occur on the surface boron doped diamond BDD anodes, and electrolytes, and explains mechanisms of organic compounds mineralization.
Electrochemical oxidation technology has gained significant attention in wastewater treatment back to the 1970s, thanks to its environmentally friendly and efficient characteristics. When coupled with flocculation, biochemistry, membrane treatment, and other technologies, it offers remarkable advantages and promising prospects for the deep purification and treatment of highly concentrated refractory wastewater.
Utilizing boron-doped diamond as the electrode anode material, electrochemical oxidation technology can effectively degrade organic compounds through direct and indirect oxidation processes. Direct oxidation involves the removal of organic matter by adsorbing organic pollutants onto the anode surface through electron transfer. Indirect oxidation, on the other hand, involves the removal of organic pollutants by generating active intermediates or high oxidizing metal oxides on the anode surface.
Is BDD Electrode Better Than Other Electrode Materials For Wastewater Treatment?
boron-doped diamond (BDD) electrodes are non-active electrode materials thanks to the unique SP3/SP2 structure. has a high oxygen evolution overpotential, meaning it requires a significantly large potential to initiate the oxygen evolution reaction (OER), making it particularly useful for applications where a high level of oxidation is needed without unwanted side reactions due to its exceptional stability and wide potential window.
Oxygen evolution overpotential (V vs. SHE) comparison between conventional electrode materials and boron doped diamond BDD electrode demonstrated that Titainium/Boron doped diamond electrode performed much higher oxygen evolution overpotential and oxidation power than MMO electrode and conventional electrode material, therefore boron doped diamond BDD anodes can maximum electrochemical generation of hydroxyl radicals. These two charts demonstrate comparison of potential and oxygen evolution overpotential between boron doped diamond BDD electrode and conventional electrodes.
Advantages of boron doped diamond BDD electrode for wastewater treatment:
The sore electrode material with the largest oxygen evolution potential and highest hydroxyl radicals generation efficiency
With unmatched oxygen evolution overpotentials, wider potential window Boron doped diamond BDD electrode can maximum electro genreation of reactive oxygen species, especially hydroxyl radicals, hydroxyl radicals have an unique characteristic, that is to mineralize reclatriant organic compounds in a non-selective nature, the minralization processes could be optimized with proper pH value, electrode surface area, and current density, temperature, electrochemical reactor cell design, pollutant concentration, conductivity and etc,. Hydroxyl radicals are the second most active oxidizing agents that performed unmatched chemical deterioration and released constant organic molecules mineralization, breaking these compounds into carbon dioxide, water, and etc.
