Microplastic (MP) accumulation in the environment is accelerating rapidly, which has led to their effects on both ecosystem and human life garnering much attention. This study first examine degradation of high-density polyethylene (HDPE) MPs via photoelectrocatalysis (PEC) using a TiO2-modified boron-doped diamond (BDD/TiO2) photoanode. was divided into three stages: (i) preparation photoanode through electrophoretic deposition synthetic TiO2 nanoparticles BDD electrode; (ii) characterization modified electrochemical, structural, optical techniques; (iii) HDPE by electrochemical oxidation bare electrodes under dark UV light conditions. The results indicate that PEC technique degraded 89.91 ± 0.08% 10-h reaction more efficient at lower current density (6.89 mA cm−1) with BDD/TiO2 compared BDD.

In this study, the applicability of an integrated-hybrid process was performed in a divided electrochemical cell for removing organic matter from polluted effluent with simultaneous production green H2. After that, depolluted water reused, first time, cathodic compartment once again, same to be viable environmental alternative converting into energy (green H2) higher efficiency and reasonable cost requirements. The H2 (Ni-Fe-based steel stainless (SS) mesh as cathode), concomitance oxidation (EO) wastewater anodic (boron-doped diamond (BDD) supported Nb anode), studied (by applying different current densities (j = 30, 60 90 mA cm−2) at 25 °C) divided-membrane type driven by photovoltaic (PV) source. results clearly showed step, anodically treated cm−2 180 min reached high-quality parameters. Meanwhile, greater than 1.3 L, Faradaic 100%. Then, second reused again new electrodes under experimental conditions. that reuse is sustainable strategy produce when compared electrolysis using clean water. Finally, two implied benefits proposed are cleanup, both which equally significant sustainable. possible use energetic carrier developing nations final point about sustainability improvements. This win-win solution.

The application of sonoelectrochemical (SEC) oxidation technique involving the incorporation ultrasound irradiation into an electrochemical system has found enormous success for various purposes, especially organic synthesis and water treatment. Although its industrial towards removal contaminants in is not popular, on laboratory scale often attributed to physical chemical effects. These effects arise from influence irradiation, thus eliminating electrode passivation or fouling, improving mass transfer enhancing reactive oxygen species (ROS) generation. continuous activation surface, improved reaction kinetics other associated advantages are equally occasioned by acoustic streaming cavitation. This review hereby outlines common ROS generated SEC pathways their Furthermore, classes materials commonly employed as anodes prominent operational parameters performance degradation pollutants extensively discussed. Hence, this study seeks broaden significant promises offered environmentally sustainable technology advances treatment pollution remediation.

Boron-doped diamond electrodes (BDDEs) offer a highly efficient pathway to mineralize recalcitrant compounds due their reduced energy requirements, fewer chemical inputs, and mechanical stability. In this work, the electrochemical degradation of paraquat (PQ) diquat (DQ) was studied using an undivided cell (Condiacell®-type) at circumneutral pH, under galvanostatic control. The roles applied current density, volumetric flow rate, herbicide concentration were systematically through central composite design (CCD) closed-flow reaction setup. Under best operating conditions (i.e., for PQ: 1.6 mA/cm2, 80 mL/min, 70 mg/L; DQ: 1.5 73 mg/L), spectrophotometric analysis evidenced that herbicides satisfactorily removed (ca. 100%) while mineralization degrees above 90%. Furthermore, produced effluents yielded significant increases in seed germination root length, which suggest reduction toxicity. Energy consumptions 0.13 0.18 kWh/g TOC are reported with cells PQ DQ treatments, respectively. treatments by electrooxidation estimated emit nearly 2.7 38.9 kg CO2/m3 water treated, cost around USD 250/m3. Carbon emissions could be greatly decreased (0.28 CO2/m3) (0.40 if electricity generated from renewable resources. Although study suggests use BDDE can considered as green alternative agrochemical removal lower carbon emissions, environmental profile process is determined degree renewability electrical grid each country or region.
