Generation of hydroxyl radicals from reactions between a dimethoxyhydroquinone and iron oxide nanoparticles.

ABSTRACT: The hydroxyl radical (·OH) is a powerful oxidant that is produced in a wide range of environments via the Fenton reaction (Fe²⁺  + H₂O₂ → Fe³⁺  + ·OH + OH^-). The reactants are formed from the reduction of Fe³⁺ and O₂, which may be promoted by organic reductants, such as hydroquinones. The aim of this study was to investigate the extent of ·OH formation in reactions between 2,6-dimethoxyhydroquinone (2,6-DMHQ) and iron oxide nanoparticles. We further compared the reactivities of ferrihydrite and goethite and investigated the effects of the O₂ concentration and pH on the generation of ·OH. The main finding was that the reactions between 2,6-DMHQ and iron oxide nanoparticles generated substantial amounts o
