Quantitative spin-trapping ESR investigation on reaction of hydroxyl radical and selected scavengers by a newly developed flow-injection ESR system
A new flow-injection ESR system (FI-ESR) special for the quantitative spin-trapping ESR measurements is developed to estimate the second-order rate constants (k(s)) of the reaction between hydroxyl radical and selected scavengers, glycine, mannitol, and 4-hydroxycoumaric acid. The k(s) values of these scavengers show reasonable agreement with those evaluated by pulse radiolysis method.
