This powerpoint presentation begins by providing a brief overview of previous estimations of OH-EfOM rates, and then presents research goals that include the following: measure the reaction rate constant between OHand EfOM, bulk samples anddifferent sites; and,evaluate the use of EfOM properties to predict theobtained reaction rate constants. The experimental design consisted of the following: evaluate EfOM reactivity towards OH;collect samples at different reuse utilities; measure reaction rate constants;characterize EfOM; and, theemphasis is on bulk characterization (i.e., no isolation). Presentation summary includes the following: quantification of the OH-EfOM second order rate constantresulted in a better understanding of scavenging capacity;established a model relating EfOM properties to OH-EfOMreaction rate constant; and,examined the effect of oxidation on the rates which resulted in no effect. Includes tables, figures.
