Abstract
The present study focuses on photoassisted advanced oxidation processes AOPs with strongly enhanced electron transfer for degradation of nitrophenolic compounds in aqueous medium The effectiveness of these processes was estimated based on the pseudofirst order rate constant k determined from highperformance liquid chromatography The degradation of four different nitrophenolic compounds was systematically studied using selected AOPs these four compounds were nitrophenol dinitrophenol trinitrophenol and trinitroresorcin It was observed that the combination of ultraviolet light with hydrogen peroxide H2O2 enhanced and maintained hydroxyl radicals and therefore increased the conversion yield of organic pollutants These AOPs provided efficient and green removal of stable organic toxins found in a wide range of industrial wastewater
