Kinetic concepts to quantify the role of oxidants and photooxidants in natural waters and water treatment
- Swiss Federal Institute for Environmental Science and Technology, Duebendorf (Switzerland)
Research performed during the last two decades has led to a significant evolution of reaction kinetic concepts to estimate the role of reactive oxidants and photooxidants in natural waters and for water treatment. Although many reaction-rate data for oxidants such as OH and HO{sub 2}/O{sub 2}{sup -} radicals, O{sub 2} and O{sub 3} or ClO{sub 2} had been compiled before, these were rather selected to elucidate other areas of research and applications. Their critical applications for describing reactions of interest for aqueous chemistry has then required to extend the compilations of rate data: (1) to include more reactions of relevance in aqueous media, (2) to critically account for the aqueous speciations, (3) to experimentally characterise the environmental factors controlling the steady-state concentration of different oxidants, (4) to formulate models useful for computing predictions and allowing for critical experimental tests, and (5) to allow for a unified concept for teaching environmental chemistry that better approaches the concepts of classical chemistry.
