An Empirical, Quantitative Approach to Predict the Reactivity of Some Substituted Aromatic Compounds Towards Reactive Radical Species (Cl2-·, Br2-·, ·NO2, SO3-·, SO4-·) in Aqueous Solution (3 pp)

Abstract Background, Aim and Scope   The reactions between organic compounds and reactive radicals in solution define the fate of the parent molecules in the natural environment and in the processes of water and wastewater treatment. However, the reaction kinetics is known for a limited number of compounds only. For this reason, various attempts have been made to correlate chemical structure and reactivity, in order to foresee the reactivity of compounds that have not yet been tested. Many examples of this kind are reviewed in the literature, concerning reactions with various important oxidising species (·OH, CO3-·, RO·, ROO·, excited triplet states, 1O2, ClO2, H2O2, O3, CrO42-, MnO4-).
