Diuron degradation using three-dimensional electro-peroxone (3D/E-peroxone) process in the presence of TiO 2/GAC: Application for real wastewater and optimization using RSM-CCD and ANN-GA approaches. CHEMOSPHERE 2021; 266:129179. [PMID: 33307415 DOI: 10.1016/j.chemosphere.2020.129179] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 11/28/2020] [Accepted: 11/30/2020] [Indexed: 06/12/2023]
Abstract
The present study investigates the efficiency of a three-dimensional electro-peroxone (3D/E-peroxone) reactor filled with TiO2-GAC in removing diuron from aqueous solution and in the remediation of real pesticide wastewater. The behavior of the system in terms of the effect of independent variables on diuron was investigated and optimized by RSM-CCD and ANN-GA methods. Both approaches proved to have a very good performance in the modeling of the process and determined the optimum condition of the independent variables as follows: initial pH = 10, applied current = 500 mA, supporting electrolyte = 0.07 M, ozone concentration = 10 mg L-1, and reaction time = 10 min. The 3D/E-peroxone process achieved a synergistic effect in diuron abatement and reduced significantly energy consumption, as compared to its individual components. H2O2 concentration generated in the electrolysis system was notably increased in the presence of TiO2-GAC microparticles. The BOD5/COD ratio of the real pesticide wastewater increased from 0.049 to 0.571 within 90 min treatment. Giving to the considerable enhancement of the biodegradability of the wastewater, this study strongly suggests that the 3D/E-peroxone process can be considered as a promising pretreatment step before a biological treatment process to produce intermediates which are more easily degradable by microorganisms.

Abstract
Wastewaters containing recalcitrant and toxic organic pollutants are scarcely decontaminated in conventional wastewater facilities. Then, there is an urgent challenge the development of powerful oxidation processes to ensure their organic removal in order to preserve the water quality in the environment. This review presents the recent development of an electrochemical advanced oxidation process (EAOP) like the photoelectro-Fenton (PEF) process, covering the period 2010-2019, as an effective treatment for wastewater remediation. The high oxidation ability of this photo-assisted Fenton-based EAOP is due to the combination of in situ generated hydroxyl radicals and the photolytic action of UV or sunlight irradiation over the treated wastewater. Firstly, the fundamentals and characteristics of the PEF process are described to understand the role of oxidizing agents. Further, the properties of the homogeneous PEF process with iron catalyst and UV irradiation and the benefit of sunlight in the homogeneous solar PEF one (SPEF) are discussed, supported with examples over their application to the degradation and mineralization of synthetic solutions of industrial chemicals, herbicides, dyes and pharmaceuticals, as well as real wastewaters. Novel heterogeneous PEF processes involving solid iron catalysts or iron-modified cathodes are subsequently detailed. Finally, the oxidation power of hybrid processes including photocatalysis/PEF, solar photocatalysis/SPEF, photoelectrocatalysis/PEF and solar photoelectrocatalysis/SPEF, followed by that of sequential processes like electrocoagulation/PEF and biological oxidation coupled to SPEF, are analyzed.

Abstract
The imidacloprid was mineralized by heterogeneous photo-Fenton process in a three-phase fluidized bed reactor using waste iron oxide as catalyst. The effects of catalyst loading, dosage of H2O2 and pH were investigated to determine the optimal experiments conditions. The results revealed that TOC removal efficiency increases with an increase in H2O2 dosage of up to 105.0 mM, an increase in catalyst dosage from 1.0 to 5.0 g L-1, and a decrease in pH from 5.0 to 3.5. Under the optimal conditions, 97.7% TOC removal was achieved in 6 h under 254-nm UV irradiation. Moreover, recycling experiments indicated that the waste iron oxide had a good stability and the TOC removal of pesticide yielded more than 80% under the fourth recycles.

Abstract
BACKGROUND Chloronicotinic insecticide are a class of pesticides that are commonly used as insecticides. Among the frequently used chloronicotinic pesticide, imidacloprid (IM) was developed in 1986. The residual of this insecticide or any pesticides may have serious public health threats. METHODS Both degradation and mineralization of the imidacloprid (IM) in aqueous solution was studied under various experimental conditions using different advanced oxidation processes namely, ultraviolet C (UVC), UVC + TiO2, and UVC + ZnO. All the experiments were performed using a lab-scale batch photoreactor with a working volume of 100 mL equipped with low-pressure mercury vapor lamp (9 W, 18 cm long, Philips Co.), emitting UV radiation with maximum intensity at 254 nm. The possible intermediates and a reaction pathway for photocatalytic degradation of the IM were also evaluated. RESULTS It was observed that under optimal condition for UVC/TiO2 process (C0 = 100 mg/L, pH = 7.5, t = 20 min, TiO2 dose = 100 mg/L), IM was effectively degraded (88.15%) and followed the first order kinetics model. The degradation efficiency increased with increasing of illumination time and is more favorable in alkaline pH compared to acidic pH. Degradation of the IM in photocatalytic process was compared with photolysis showing a significant synergy effect in the case of the photocatalytic degradation process, leading at 20 min illumination time to a 36.7% increase of the IM removal efficiency in comparison to the single UVC. The GC/MS chromatograms before and after treatment confirmed the effectiveness of the UVC/TiO2 process in simplifying the nature of IM and its conversion to more simple and degradable compounds. CONCLUSION The heterogeneous UVC/TiO2 process was found to be an efficient chemical-less method that is appropriate for degradation of IM from aqueous phase.

Abstract
The photodegradation of the neonicotinoid insecticide nitenpyram (NPY) under UV and solar irradiation has been investigated in water solutions in order to assess its persistence in the environment and its transformation into other potentially more toxic species. Time-courses were followed by ultra-high performance liquid chromatography-tandem mass spectrometry. Transformation products (TPs) were identified by their accurate product ion spectra, obtained with a quadrupole time-of-flight mass spectrometer after their liquid chromatographic separation. NPY was rapidly photodegraded under all the investigated conditions, following a first-order model and with half-lives varying from seconds to <10 min. Quantum yields were between 0.0385 and 0.0534 mol einstein-1. The identified TPs, some of them reported for the first time in this study, were formed through different reactions involving the nitro-ethylene moiety of the parent insecticide. Conversely to the lability of NPY, its TPs were more photo-stable in both ultrapure and river water. Moreover, in-silico toxicity assessment showed that most of them display a higher acute toxicity than NPY.

Abstract
This study examined the photo-assisted electrochemical degradation and mineralization of the antibiotic contaminant sulfamethoxazole (SMX). All the experiments were perform using a flow electrolytic cell, in which the influence of the current density (10-60 mA cm-2) and sodium chloride (0.02-0.10 mol L-1) in the supporting electrolyte composition was analyzed. The results showed that the total SMX and 50% TOC removal was achieved in the current density range used. As expected, the degradation kinetics presented a pseudo first order behavior and the rate constant increased from 0.05 min-1 to 0.50 min-1 as the current density raised from 10 to 60 mA cm-1. In addition, the values of the electrical energy per order (EEO) increased from 0.67 to 1.06 kW/hm-3 order-1 as the current density increased from 10 to 60 mAcm-2 and drop from 8.82 to 0.57 kW/hm-3 order-1 at supporting electrolyte concentration of 0.02-0.1 mol L-1. The reaction intermediates identified by liquid chromatography-mass spectrometry allowed proposing a mechanism for the degradation. The use of photo assistance in the electrochemical process involved simultaneous reactions, for example, aromatic ring substitutions and hydroxylation. These reactions led to aromatic rings opening that generated simpler organic molecules, making possible the mineralization of the SMX molecule. Probable degradation pathways were proposed and discussed. Comparison of the efficiencies of the photocatalytic, electrochemical (EC) and photo-assisted electrochemical (PAEC) techniques revealed that the combined process showed a synergism for TOC removal.

Abstract
The removal of radiocontrast agent diatrizoic acid (DIA) from water was performed using photo-Fenton (PF) process. First, the effect of H2O2 dosage on mineralization efficiency was determined using ultraviolet (UV) irradiation. The system reached a maximum mineralization degree of 60 % total organic carbon (TOC) removal at 4 h with 20 mM initial H2O2 concentration while further concentration values led to a decrease in TOC abatement efficiency. Then, the effect of different concentrations of Fenton's reagents was studied for homogeneous Fenton process. Obtained results revealed that 0.25 mM Fe(3+) and 20 mM H2O2 were the best conditions, achieving 80 % TOC removal efficiency at 4 h treatment. Furthermore, heterogeneous PF treatment was developed using iron-activated carbon as catalyst. It was demonstrated that this catalyst is a promising option, reaching 67 % of TOC removal within 4 h treatment without formation of iron leachate in the medium. In addition, two strategies of enhancement for process efficiency are proposed: coupling of PF with electro-Fenton (EF) process in two ways: photoelectro-Fenton (PEF) or PF followed by EF (PF-EF) treatments, achieving in both cases the complete mineralization of DIA solution within only 2 h. Finally, the Microtox tests revealed the formation of more toxic compounds than the initial DIA during PF process, while, it was possible to reach total mineralization by both proposed alternatives (PEF or PF-EF) and thus to remove the toxicity of DIA solution.
