Can we calculate radical contribution using initial reaction rates instead of rate constants in UV/oxidant systems, particularly if the reaction shows unusual behavior at high concentrations of organic matter, affecting the rate constants?
That's a really great question, and I've had this problem, but my method is to assign the proportion of different living species by degradation contribution
Yes, radical contribution can be calculated using initial reaction rates by analyzing the rate of the reaction under conditions that favor radical generation. Comparing the reaction rates with and without radical scavengers helps estimate the radicals' contribution. This method relies on the assumption that scavengers selectively inhibit radical pathways. Kinetic models or simulations further support such analyses.
