Summary: Electrocatalytic oxidation (ECO) is a highly efficient and environmentally friendly method for water treatment. This study focuses on the preparation of high-performance anodes with long service lifetimes. Porous Ti/RuO2-IrO2@Pt, Ti/RuO2-TiO2@Pt, and Ti/Y2O3-RuO2-TiO2@Pt anodes were fabricated using modified micro-emulsion and vacuum impregnation methods. These anodes exhibited large electrochemically active areas and long service lives. The Ti/Y2O3-RuO2-TiO2@Pt anode showed the highest degradation efficiency for tetracycline and consumed the lowest energy.

Summary: The electrocatalytic properties of Ti/RuO2-SnO2 and Ti/RuO2-IrO2 anodes in different electrolytes were studied for aniline degradation. Ti/RuO2-SnO2 showed higher activity in Na2SO4 electrolyte, while Ti/RuO2-IrO2 was more effective in NaCl electrolyte. The presence of Fe2+ can decrease TOC removal efficiency, especially for Ti/RuO2-SnO2.

Summary: A Ti/TiO2-NTs/PbO2 electrode was successfully fabricated and showed superior electrochemical performance in degrading reverse osmosis concentrate from local printing and dyeing mills. The introduction of TiO2-NTs enhanced electron transport and facilitated the generation of hydroxyl radicals, leading to more effective degradation under weakly alkaline conditions. The electrode retained its COD removal capacity and morphology, with no detection of Pb(II) even after 10 cycles of continuous use.

Summary: The electrochemical chlorination of urea to CO2 and N-2 end-products, via active-chlorine-mediated oxidation under nearly neutral conditions, is an effective treatment for medium-concentrated urea-containing wastewater. A novel flow reactor integrated with three-dimensional hierarchically porous Ru/RuO2 architectures anchored on a Ti mesh was designed. The hierarchically macroporous electrode can create sufficient exposure of catalytically active sites and facilitate the microscopic mass transport and diffusion inside the active layer, thereby contributing to the increased removal efficiency of urea-N and ammonia-N.

Summary: The study evaluated urinary parabens concentration among 117 Iranian pregnant women in their first trimester. Methylparaben, ethylparaben, propylparaben, and butylparaben were detected with certain median concentrations, and significant associations were found with variables such as educational level, plastic packaging, physical activity, sampling season, and use of personal care products. This suggests that Iranian pregnant women are at high risk of paraben exposure.

Summary: In this study, magnetic bentonite and Ti/TiO2 nanotube/PbO2 were investigated as particle electrodes and anode of three dimensional electro-Fenton process for the degradation of diclofenac and naproxen. It was found that the 3DEF process had higher removal efficiency compared to adsorption and electrochemical processes at neutral pH. The production of hydroxyl radicals was the main factor contributing to the high efficiency. The optimal conditions for the degradation were determined and the stability and reusability of the electrodes were confirmed.

Summary: Biomass waste from pomegranate husk was converted into a carbon sheet electrode, which was effective in removing 4-chlorophenol from water. The highest removal efficiency was observed at pH 6.0, applied voltage of 1.5 V, ionic strength of 0.85 mM, and contact time of 270 min. Increasing the applied voltage significantly improved the removal efficiency, while increasing the initial 4CP concentration decreased the efficiency. The carbon electrode showed a high sorption capacity and potential for removing other phenolic compounds.

Summary: This research explores the degradation of 2,4-dichlorophenol (2,4-DCP) using lab-scale hydrodynamic cavitation (HC) with the addition of zero-valent iron (Fe-0) as a catalyst for sulfate radical (SO4 center dot-) generation. The degradation efficiency was higher at acidic pH and depended on the Fe-0 and sulfite (SO32-) dose. Under optimal conditions, the Fe-0/HC/sulfite approach significantly enhanced the degradation efficiency compared to HC alone. (OH)-O-center dot and SO4 center dot- radicals played a dominant role in the degradation process. The turbulence model showed that increasing inlet pressure intensified bubble collapse due to higher turbulence tension.
