Short summary
This article describes a comprehensive investigation of the aqueous oxidation of 4-nitrophenol (4NP) by hydroxyl radicals (OH). The reaction was carried out in a laboratory photoreactor. We report the formation of key intermediates under different pH conditions and the evolution of the light absorption of the reaction solution. The results provide new insights into the formation and removal (chemical bleaching) of light-absorbing organic aerosols (atmospheric brown carbon).
