Photoelectrocatalytic Surfactant Pollutant Degradation and Simultaneous Green Hydrogen Generation

Industrial & Engineering Chemistry Research, Год журнала: 2023, Номер unknown

Опубликована: Июнь 2, 2023

For the first time, we demonstrate a photoelectrocatalysis technique for simultaneous surfactant pollutant degradation and green hydrogen generation using mesoporous WO3/BiVO4 photoanode under simulated sunlight irradiation. The materials properties such as morphology, crystallite structure, chemical environment, optical absorbance, bandgap energy of films are examined discussed. We have tested anionic type (sodium 2-naphthalenesulfonate (S2NS)) cationic surfactants (benzyl alkyl dimethylammonium compounds (BAC-C12)) model pollutants. A complete removal S2NS BAC-C12 at 60 90 min, respectively, by applying 1.75 V applied potential vs RHE to circuit, 1 sun was achieved. An interesting competitive phenomenon photohole utilization observed between adsorbed water. This led formation H2O2 from water alongside (anode) evolution (cathode). No byproducts were after direct mediated surfactants, implying its advantage over other AOPs biological processes. In cathode compartment, 82.51 μmol/cm2 71.81 gas generated during process, potential.

Amphiphilic Janus Nanoparticles for Effective Foam Fractionation of Perfluorooctanoic Acid (Pfoa): Effect of Surface Modifications

Опубликована: Янв. 1, 2025

Perfluorooctanoic acid (PFOA), a persistent organic pollutant, is gaining attention for its detrimental effects on human health and ubiquity in aquatic environments. Herein, we introduce novel foam fractionation method that uses Janus nanoparticles as stabilizers collectors the efficient removal enrichment of PFOA from water. The amphiphilic Janus-SiO2 (SNPs) were successfully synthesized through anisotropic modification with perfluoroalkylsilanes aminosilanes. amphiphilicity constructed F17-SNPs-N2 enhanced stability due to high detachment energy bridging mechanism. fluorine amino groups surface facilitated adsorption via fluorine-fluorine interactions, hydrophobic-hydrophobic hydrogen bonding, electrostatic attraction, supported by experimental analysis DFT calculation. We also explored mechanisms governing under different parameters. Under optimal conditions, achieved efficiencies ratios 98% 98, respectively, within bubbling duration 180 s. F17-SNPs-N2, bifunctional material fractionation, demonstrated reusability excellent performance even presence competing contaminants, highlighting broad environmental application potential. This research provides strategy designing Janus-based agents post-modification enhances our understanding behind highly fractionation.

Integrated Purification Systems for the Removal of Disinfectants from Wastewater

Membranes, Год журнала: 2025, Номер 15(2), С. 43 - 43

Опубликована: Фев. 2, 2025

The efficiency of integrated treatment systems for wastewater generated during the washing disinfectant production lines was investigated. high organic load (COD 2000 mg/L, TOC 850 mg/L) and 300 mg/L toxic benzalkonium chloride (BAC) make an environmental hazard that requires advanced treatment. Initial tests on model BAC solutions (in concentrations corresponding to those found in wastewater), using nanofiltration ultrafiltration membranes, resulted up 70% retention BAC. To enhance purification, ion exchange adsorption were introduced as post-membrane steps. In second part investigation, membrane modules characterized by best separation properties together with macroporous cation-exchange resin activated carbon into purification system treat wastewater. research carried out showed multicomponent is a complex task. Significantly lower removal (30%) achieved processes compared systems, concentration reduced 100 200 COD 120 mg/L.
