Efficient activation of peroxymonosulfate by carbon based catalysts for water purification The increasing global population has led to a growing demand for cost effective and eco friendly methods of water purification. This demand has reached a peak due to the increasing presence of impurities and pollutants in water and a growing awareness of waterborne diseases. Advanced oxidation processes (AOPs) are effective methods to address these challenges due to the generation of highly reactive radicals such as sulfate radical (SO4• ) hydroxyl radical (•OH) and or superoxide radical (•O2 ) in oxidation reactions. Relative to conventional hydrogen peroxide (H2O2) based AOPs for wastewater treatment the persulfate related AOPs are receiving increasing attention over the past decades due to their stronger oxidizing capability and a wider pH working window. Further deployment of the seemingly plausible technology as an alternative for the well established one in industry however necessitates a careful evaluation of compounding factors such as water matrix effects toxicological consequences costs and engineering ...
