This experiment introduces a method to measure the rate coefficient for the rapid reactions of transient free radicals with pollutants in an aqueous phase. Transient free radicals are generated via laser pulse photolysis and are detected using transient absorption spectroscopy. Second-order rate coefficients are obtained through the absolute rate method or relative rate method. In addition to a thorough understanding of chemical kinetics, this experiment will introduce students to innovative research in the field of environmental photochemistry of pollutants.
- Transient absorption spectroscopy,
- Laser flash photolysis,
- Carbonate radical anion,
- Hydroxyl radical
