These micropollutants persist at concentrations ranging from <strong>ng\/L to \u00b5g\/L<\/strong> even after conventional treatment, creating environmental and public health concerns.<\/p>\n<p>Peroxyacetic acid (PAA) has emerged as a promising advanced oxidation process (AOP) for pharmaceutical micropollutant degradation. Unlike traditional oxidants, PAA decomposes into acetic acid and hydrogen peroxide\u2014compounds that do not form harmful disinfection by-products. According to research published in Molecules (2026), PAA generates hydroxyl radicals through homolytic cleavage of the peroxy bond, enabling non-selective oxidation of organic compounds.<\/p>\n<h3 id=\"understanding-paa-oxidation-mechanisms\"><span class=\"ez-toc-section\" id=\"Understanding_PAA_Oxidation_Mechanisms\"><\/span>Understanding PAA Oxidation Mechanisms<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>PAA operates through multiple reaction pathways depending on activation methods:<\/p>\n<p><strong>Thermal Activation<\/strong>: Heating PAA solutions to <strong>40-60\u00b0C<\/strong> accelerates peroxy bond dissociation, increasing hydroxyl radical generation rates by approximately <strong>45%<\/strong> compared to ambient temperature conditions.
