Boron Doped Diamond BDD Electrode Applications Note

Applications ranges of BDD electrode from water treatment to water disinfection, electrochemical analysis, electrochemical surface modification, electrochemical detection. Explore laest advancement and various innovative applications of BDD electrode for its unique properties, features and advantages.

Amongst a vast range of applications, wastewater treatment is the most promising one as these electrode materials are implemented to treatment various types of bio-refractory waste streams, and complex industrial effluents for a long time.

Thanks to the high oxygen evolution potential, low background current, and robust nature, BDD electrodes, especially when act as anodes, they generate huge amount of powerful oxidizing agents, for instance hydroxyl radicals, can remove heavy metals, ammonium, a wide range of organic compounds, including PFAS, alcohols, total organic carbon(TOC), aldehydes, total ammonia nitrogen (TAN), aromatics, amines, active pharmaceutical intermediates, chemical oxygen demand (COD), BTEX, phenols, pesticides, coloration, total nitrogen and etc, from wastewater.                                                                                                                                                                                                                                                                                                                                    Water disinfection is a critical application of boron doped diamond electrode as it has higher overpotential for oxygen and hydrogen evolutions, which expedite electrochemical ozone production through water electrolysis. 

Ozone is one of the most powerful oxidizing agents, disinfection could be done in an eco-friendly manner as there will be no addition of chemicals, and no harmful chemical left. Evoaeo team have developed BDD Ozone generator, for application in food sanitization, home appliances, and swimming pool & spa disinfection.

BDD electrode has much larger potential window means there will be no significant undesired side reactions happen on the surface of BDD electrode once electrical potential applied, lower background current expedites electron transfer rate, enhances sensitivity, and improve detection reliability.

Electrochemical Oxidation Treatment Application of BDD Electrode for Specific Industrial Effluent Wastewater

Wastewater treatment is one of the prominent applications of boron doped diamond BDD electrode, here at Evoaeo, we treat complex waste streams by utilizing an innovative treatment approach/technology called electrochemical oxidation, or say electro oxidation.

Electrochemical oxidation to adopting electrical engery to accomplish oxidation and further removal of dissolved recalcitrant organic pollutants, there are two approaches within the electrochemical oxidation mechanisms, that is direct oxidation and indirect oxidation.

simultaneouslyInvolves direct oxidation where pollutants transfer electrons to the anode, or indirect oxidation via electrochemically-generated oxidants like hypochlorite or hydrogen peroxide  indiscriminate. 

Direct oxidation intialized with generation of potential differences amongst the anodes and cathodic electrodes, once electrcity applied to the electrochemical reactors/electrolytic cells, EO processes usually require direct current.                                                                                                                                                                                                                                                                  Dissolved organic pollutants will have direct contact with the immersed anode surface where undertaking direct electron transfer, a type of charge transfer reaction, these pollutants will lose electrons, disconneting their chemical bonds, therefore oxidized into inorganic compounds.

However direct oxidation processes are proven to be less effective toward some recalcitrant organic pollutants.                                                                                                                                                                                                                                                                    That is why indirect oxidation which involves generation of powerful oxidants capable of non-selective mineralizations of most recalcitrant organic pollutants with complex molecular structures are introduced simultaneously, unlike those direct electron transfers, indirec oxidation employs highly reactive, short-lived but yet highly reactive electrochemically-generated oxidants.                                                                                                                                                                                                                                      Major oxidants with the indirect oxidation are, sulfate radicals, Hydroxyl radicals (•OH), ozone, hypochlorite, hypocholorous acid, hydrogen peroxide, and etc,                                                                                                                                                                                                                                                                                                                                                                                                              Leveraging its unique electrochemical properties, BDD electrode could complete mineralize inorganic, organic, bio-refractory molecules thanks to its high overpotentials of hydrogen and oxygen evolution, which eventually increase electrochemical generation of hydroxyl radicals and Ozone, and other oxidizing agents.                                                                                                                                                                                                                                                                                                                                                    BDD electrode serves as an exceptional choice for electrodes, particularly in electrochemical treatment of industrial effluents. These electrodes can efficiently remove bio-refractory organic contaminants, pathogens, and impurities from water.
