“…•− is needed for fast and complete iprodione removal. In fact, previous work has already demonstrated that organic pollutant removal in complex matrices like water and wastewater is negatively affected by the presence of their natural ingredients [37][38][39][40][41][42][43][44][45].…”

Water contamination with various micropollutants is a serious environmental concern since this group of chemicals cannot always be removed efficiently with advanced treatment methods. Therefore, alternative chemical- and energy-intensive oxidation processes have been proposed for the removal of refractory and/or toxic chemicals. However, similar treatment performances might result in different environmental impacts. Environmental impacts can be determined by adopting a life cycle assessment methodology. In this context, lab-scale experimental data related to 100% iprodione (a hydantoin fungicide/nematicide selected as the model micropollutant at a concentration of 2 mg/L) removal from simulated tertiary treated urban wastewater (dissolved organic carbon content = 10 mg/L) with UV-C-activated persulfate treatment were studied in terms of environmental impacts generated during photochemical treatment through the application of a life cycle assessment procedure. Standard guidelines were followed in this procedure. Iprodione removal was achieved at varying persulfate concentrations and UV-C doses; however, an “optimum” treatment condition (0.03 mM persulfate, 0.5 W/L UV-C) was experimentally established for kinetically acceptable, 100% iprodione removal in distilled water and adopted to treat iprodione in simulated tertiary treated wastewater (total dissolved organic carbon of iprodione + tertiary wastewater = 11.2 mg/L). The study findings indicated that energy input was the major contributor to all the environmental impact categories, namely global warming, abiotic depletion (fossil and elements), acidification, eutrophication, freshwater aquatic ecotoxicity, human toxicity, ozone depletion, photochemical ozone creation, and terrestrial ecotoxicity potentials. According to the life cycle assessment results, a concentration of 21.42 mg/L persulfate and an electrical energy input of 1.787 kWh/m3 (Wh/L) UV-C light yielded the lowest undesired environmental impacts among the examined photochemical treatment conditions.

“…8 Many studies have focused on the evaluation of individual classical advanced oxidation systems. 9 However, the conditions and purposes of these studies are not identical, resulting in the difficulty to effectively and directly compare the differences and merits of these systems in the wastewater treatment process. Therefore, systematic comparison work is important to be conducted for the guidance of government, academic societies, and industry decision makers.…”

In this study, three electrochemical cocatalytic oxidation (EO) systems using different oxidants peroxysulfate (both PMS and PDS) and hydrogen peroxide (H 2 O 2 ) were compared. These systems were analyzed for their degradation mechanisms and pathways of organic pollutants, specifically sulfamethoxazole (SMX), carbamazepine (CBZ), and bisphenol A (BPA). Based on quenching experiments and electron paramagnetic resonance (EPR) analyses, the EO-Fe(III)-PMS system generated multiple reactive oxygen substances (ROS) including SO 4•− , • OH, and 1 O 2 . The EO-Fe(III)-PDS process primarily utilized • OH and SO 4 •−, with • OH being the dominant oxidation agent. The EO-Fe(III)-H 2 O 2 system chiefly depended on • OH, which exhibited the highest yield among the three systems. Response surface methodology (RSM) analysis suggested that the EO-Fe(III)-PMS process was less influenced by the complex water matrices. The degradation pathways for SMX, CBZ, and BPA were predicted by leveraging mass spectrometry (MS) data. Biotoxicity assessments revealed that the EO-Fe(III)-H 2 O 2 system is the most apt for SMX elimination. Meanwhile, the EO-Fe(III)-PMS system displayed environmentally friendly characteristics during CBZ oxidation compared to the other two systems. Overall results indicate the pros and cons of electrochemical catalytic systems utilizing different oxidants, offering insights into future options of treatment strategies based on their individual merits and sustainability.

“…AOPs consist of techniques such as electro-oxidation (direct or indirect), electro-coagulation, photocatalytic reactions, Fenton reactions, ozonation, etc. [ 5 , 6 ]. For instance, direct electro-oxidation involves the production of hydroxyl radicals, which can be absorbed chemically (creating various oxidation materials that aid in the breakdown of the pollutants) or physically (causing the complete decomposition of pollutant materials).…”

Water is one of the fundamental resources for the existence of humans and the environment. Throughout time, due to urbanization, expanding population, increased agricultural production, and intense industrialization, significant pollution with persistent contaminants has been noted, placing the water quality in danger. As a consequence, different procedures and various technologies have been tested and used in order to ensure that water sources are safe for use. The adsorption process is often considered for wastewater treatment due to its straightforward design, low investment cost, availability, avoidance of additional chemicals, lack of undesirable byproducts, and demonstrated significant efficacious potential for treating and eliminating organic contaminants. To accomplish its application, the need to develop innovative materials has become an essential goal. In this context, an overview of recent advances in hydrogels based on chitosan and nanocomposites and their application for the depollution of wastewater contaminated with dyes is reported herein. The present review focuses on (i) the challenges raised by the synthesis process and characterization of the different hydrogels; (ii) the discussion of the impact of the main parameters affecting the adsorption process; (iii) the understanding of the adsorption isotherms, kinetics, and thermodynamic behavior; and (iv) the examination of the possibility of recycling and reusing the hydrogels.
