“…(9)) generated in this reaction. The amount of pyrite powder added to the solution constitutes an operating parameter influencing oxidation kinetics of organic pollutants for establishment of appropriate concentration of Fe 2+ in the system and dosage of 1.0–2.0 g L −1 were found to be optimal values ,. Finally electro‐Fenton pyrite process provide performances close (even better in some cases) to that of homogeneous electro‐Fenton in addition of advantages mentioned above.…”

Over the past few decades, environmental applications of the boron‐doped diamond (BDD) electrode are reported to be vast and versatile. Applications of BDD electrodes in the field of electrochemical advanced oxidation processes (EAOPs) for the abatement of toxic persistent organic pollutants are significant, owing to the easy and effective way of treatment. This article focuses on highlighting and summarizing the applications of the BDD electrode for the treatment of different synthetic and real wastewaters, such as those involved in pharmaceuticals and personal care products, pesticides/herbicides, dyes, etc. We also review the processes and methodologies involving the synthesis of BDD electrodes and summarize the desirable characteristic features required for the application of EAOPs. Applications of BDD electrodes for the treatment of wastewater through different EAOPs, including anodic oxidation, electro‐Fenton, coupling processes such as electro‐Fenton pyrite, bioelectro‐Fenton, and their recent advancements are also discussed in detail. It envisages the greater potential for complete treatment of different toxic wastewater effluents. This Review shows that the application of BDD electrodes in the field of wastewater treatment is tremendous and proves to be a promising material for future perspectives.

Advanced Electro‐Oxidation with Boron‐Doped Diamond for Acetaminophen Removal from Real Wastewater in a Microfluidic Reactor: Kinetics and Mass‐Transfer Studies

2019

The removal of hazardous organic micropollutants in municipal wastewater treatment plants (WWTP) has become a common concern for public decision-makers and stakeholders. An advanced electro-oxidation with boron-doped diamond (BDD) anode material is proposed to remove acetaminophen as a representative micropollutant in synthetic solution. A customized microfluidic reactor was run in batch mode, and the main operating parameters (i. e. current density, interelectrode distance and solution conductivity) were optimized by minimizing the energy requirement. An optimal current density of 4 mA cm À 2 and an optimal interelectrode distance of 500 μm were newly obtained and explained. Mass transport limitation was observed at lower gaps, with a 3.4-fold decrease in the mass transfer coefficient from 500 μm to 50 μm intervals. In addition, the kinetics of degradation decreased dramatically after a certain electrolysis time. This was attributed to the increase in gas bubble production with treatment time. An increase in the solution conductivity from 0.23 to 2.0 mS cm À 1 increased the degradation rate efficiency twofold and decreased the specific energy from 0.88 to 0.17 kWh g À 1 at 85 % acetaminophen decay yield. The influence of a real matrix from low-conductivity reclaimed WWTP (0.86 mS cm À 1 ) highlighted slightly lower kinetics of degradation, but similar energy efficiency until 60 % of pollutant degradation and higher energy efficiency than in conventional macro-reactors.[a] Dr. E. Mousset, M. Puce, Dr. M.-N. Pons
