Enhanced favipiravir drug degradation using the synergy of PbO-based anodic oxidation and Fe-MOF-based cathodic electro-Fenton.

Favipiravir (FAV) is a widely utilized antiviral drug effective against various viruses, including SARS-CoV-2, influenza, and RNA viruses. This article aims to introduce a novel approach, known as Linear-Paired Electrocatalytic Degradation (LPED), as an efficient technique for the electrocatalytic degradation of emerging pollutants. LPED involves simultaneously utilizing a carbon-Felt/Co-PbO anode and a carbon-felt/Co/Fe-MOF-74 cathode, working together to degrade and mineralize FAV.

Facile fabrication of amino-functionalized MIL-68(Al) metal-organic framework for effective adsorption of arsenate (As(V)).

An amino-functionalized MIL-68(Al) metal-organic framework (amino-MIL-68(Al) MOF) was synthesized by solvothermal method and then characterized by FESEM, XRD, FTIR, EDX-mapping, and BET-BJH techniques. In order to predict arsenate (As(V)) removal, a robust quadratic model (R > 0.99, F-value = 2389.

Application of a fluidized three-dimensional electrochemical reactor with Ti/SnO-Sb/β-PbO anode and granular activated carbon particles for degradation and mineralization of 2,4-dichlorophenol: Process optimization and degradation pathway.

A three-dimensional electrochemical reactor with Ti/SnO-Sb/β-PbO anode and granular activated carbon (3DER-GAC) particle electrodes were used for degradation of 2,4-dichlorophenol (2,4-DCP). Process modeling and optimization were performed using an orthogonal central composite design (OCCD) and genetic algorithm (GA), respectively. Ti/SnO-Sb/β-PbO anode was prepared by electrochemical deposition method and then its properties were studied by FESEM, EDX, XRD, Linear sweep voltammetry and accelerated lifetime test techniques.

Electrocatalytic degradation of diuron herbicide using three-dimensional carbon felt/β-PbO anode as a highly porous electrode: Influencing factors and degradation mechanisms.

Traditional planar PbO anodes have been used extensively for the electrocatalytic degradation process. However, by using porous PbO anodes that have a three-dimensional architecture, the efficiency of the process can be significantly upgraded. In the current study, carbon felt (CF) with a highly porous structure and a conventional planar graphite sheet (G) were used as electrode substrate for PbO anodes.

Sonophotocatalytic treatment of AB113 dye and real textile wastewater using ZnO/persulfate: Modeling by response surface methodology and artificial neural network.

The present study investigates the synergistic performance of the sonophotolytic-activated ZnO/persulfate (US/UV/ZnO/PS) process in the decolorization of acid blue 113 (AB113) dye from aqueous solution and its feasibility for the treatment of real textile wastewater. Decolorization of AB113 solution was modeled by central composite design-response surface methodology (CCD-RSM) and artificial neural network (ANN) approaches and optimized by CCD-RSM and genetic algorithm (GA) approaches. Statistical metrics indicated that both CCD-RSM and ANN approaches seemed satisfactory.

Thermochemical degradation of furfural by sulfate radicals in aqueous solution: optimization and synergistic effect studies.

In this study, thermochemical degradation of furfural by sulfate radical has been investigated to find the best-operating conditions. For this purpose, the response surface methodology (RSM) based on central composite design (CCD) was applied to optimize the five independent variables of thermally activated persulfate (TAP)/nZVI oxidation process including pH, PS concentration, furfural concentration, nZVI dosage, and heat. The ANOVA results ("P > F value" < 0.
