Advanced Oxidation Processes for Water and Wastewater Treatment
This community develops chemical and catalytic methods to break down organic pollutants in drinking water and wastewater, using oxidants like peroxymonosulfate, ozone, and chlorine.
The work centers on activating oxidants to generate reactive oxygen species, including hydroxyl radicals and singlet oxygen, for the efficient degradation of persistent contaminants such as antibiotics, dyes, and pharmaceuticals. Recurring methods include peroxymonosulfate activation, catalytic ozonation, electrochemical oxidation, and Fenton-like reactions using iron or other metal catalysts. Researchers frequently investigate the mechanisms of radical and non-radical pathways, electron transfer processes, and the formation of disinfection byproducts. The goal is to enhance the removal of organic matter and specific pollutants like tetracycline and bisphenol A from aqueous solutions, often through heterogeneous catalysis and advanced oxidation processes.
The largest share of the community's output is found in chlorine research, accounting for 3.8% of all chlorine research, and 6,597 papers here. Bromine research also represents a significant portion, with 3.0% of its total research appearing in this group.
The community comprises 36,577 papers, published primarily in Water Research, Chemical Engineering Journal, and Journal of Water Process Engineering.
Recent work continues to focus on the mechanisms of peroxymonosulfate activation and the role of singlet oxygen in advanced oxidation processes. New studies explore single-atom catalysts, electrocatalytic systems, and the degradation of specific antibiotics and dyes, with a strong emphasis on understanding both radical and non-radical pathways for pollutant removal.
