Summary: Pharmaceutical residues as emerging pollutants in the aquatic environment have become a growing concern. This paper explores the use of ferrate oxidation combined with anodic oxidation or electro-Fenton processes for the degradation of a model pharmaceutical compound. The results show that using ferrate as a pre-oxidation step and as an iron source for the electro-Fenton process is the most promising treatment strategy, leading to fast degradation, low formation of aromatic by-products, and a significant decrease in acute toxicity.

Summary: Conventional wastewater treatment plants have a limited ability to remove recalcitrant and toxic organic pollutants. Developing powerful oxidation technologies is crucial for preserving water quality. The solar photoelectro-Fenton (SPEF) process proposed by our laboratory in 2007 has proven to be an effective and cost-efficient method for destroying common organic pollutants. This review summarizes the advances in SPEF technology up to 2022, highlighting its high oxidation power due to the simultaneous action of hydroxyl radicals and sunlight photolysis.

Summary: Antibiotics are widely used to fight and heal bacterial diseases in animals and humans worldwide. However, they have been detected at low concentrations in natural waters, posing potential health risks and causing alterations in food chains and increased resistance to bacterial infection. Conventional wastewater treatment plants struggle to effectively remove antibiotics due to their high stability. The electro-Fenton (EF) process, as an advanced oxidation process, shows promise for the destruction of antibiotics. This review provides a comprehensive analysis of the application of EF in treating synthetic and real wastewaters contaminated with common antibiotics from 2017 to 2021.

Summary: Copper hexacyanocobaltate was electro-deposited on amino-graphene-coated indium-tin-oxide glass to form a multifunctional heterogeneous catalyst, which was utilized to establish a novel heterogeneous photo-electro-Fenton-like system capable of generating hydrogen peroxide and hydroxyl radical simultaneously. The system showed high productivity of hydroxyl radicals and efficient degradation of levofloxacin in neutral media.

Summary: This study investigated the production of hydroxyl radicals (.OH) from solid humic acid during oxidation. The results demonstrated that solid humic acid transferred electrons to oxygen, leading to the generation of .OH. The modeling results also confirmed that reduced solid organic matter played a significant role in .OH production.

Summary: Fenton reactions, classified as homogeneous and heterogeneous, are efficient processes used in water remediation. Heterogeneous Fenton processes, using solid catalysts containing iron instead of dissolved iron, have shown higher catalytic activity compared to unsupported iron oxides. Iron-containing silica composites have been widely used for the removal of organic pollutants from aqueous solutions.

Summary: Mn(II) was found to accelerate the Fenton reaction by participating directly and catalytically in the Fe(III)/Fe(II) redox cycle in the presence of picolinic acid (PICA) as an assisting agent. Mn(II) accelerated Fe(III) reduction, superoxide radical formation, and hydroxyl radical formation, but the proposed Mn(II/III)-H2O2 redox cycle was shown to be insignificant. Instead, Mn(II) initially complexes with a ferric hydroperoxo species, followed by intramolecular electron transfer to give Fe(II) and MnO2+. This scheme can be applied to other Fenton-type systems. These findings will be valuable for the design of practical and sustainable Fenton-based advanced oxidation processes (AOPs) using Mn(II) in combination with chelating agents.

Summary: This study investigated the use of conventional and CTAB-aided coagulation-filtration processes for the removal of LAS. The results showed that CTAB formed aggregates with LAS, and the effectiveness of the process depended on the electrostatic interactions between the hydroxide floc and LAS or CTAB-LAS aggregate. The optimal coagulation pH and CTAB/LAS molar ratio varied depending on the conditions. A lower coagulation pH and a CTAB/LAS molar ratio < 1 were recommended for LAS removal.
