Special Issue Information

Dear Colleagues,

Advanced oxidation processes (AOPs) based on the generation of high reactive species in solutions such as radicals, holes, and electrons are used for chemical and biological contamination treatment with the final goal of water remediation.

In fact, efficient processes based on electrochemical, photochemical, metal, and thermal activations but also water–plasma are used to improve the degradation of contaminants of emerging concern (CECs) in water matrices.

Researchers working in the field of environmental and engineering chemistry are invited to contribute with original works and reviews.

Abstract

Losartan, an angiotensin II receptor antagonist frequently detected in wastewater effluents, poses considerable risks to both aquatic ecosystems and human health. Seeking to address this challenge, advanced oxidation processes (AOPs) emerge as robust methodologies for the efficient elimination of such contaminants. In this study, the degradation of Losartan was investigated in the presence of activated peroxymonosulfate (PMS), leveraging ferrous iron as a catalyst to enhance the oxidation process. Utilizing advanced analytical techniques such as NMR and mass spectrometry, nine distinct byproducts were characterized. Notably, seven of these byproducts were identified for the first time, providing novel insights into the degradation pathway of Losartan. The study delved into the kinetics of the degradation process, assessing the degradation efficiency attained when employing the catalyst alone versus when using it in combination with PMS. The results revealed that Losartan degradation reached a significant level of 64%, underscoring the efficacy of PMS/Fe(II) AOP techniques as promising strategies for the removal of Losartan from water systems. This research not only enriches our understanding of pollutant degradation mechanisms, but also paves the way for the development of sustainable water treatment technologies, specifically targeting the removal of pharmaceutical contaminants from aquatic environments.
