Peracetic acid activation using heterogeneous catalysts for environmental decontamination: A review

Abstract

Water pollution has become more severe due to improper discharge of pollutants in the natural water systems. Catalytic activation of peracetic acid (PAA) emerged as a promising treatment method to decontaminate organic pollutants. This review aims to elucidate the latest advances in the catalytic PAA activation covering a brief fundamental of the catalytic process, catalyst design and influence of key parameters on the performance of the system, such as pH, catalyst loading, PAA dosage, and interfering species. Finally, the prospects such as materials design, operational issues and environmental implications are proposed to advance this research field to a higher level.
