A Novel and Convenient Assay for the Determination of OH Produced by Fenton Reaction
摘要:
A novel, simple and convenient method for the determination of hydroxyl radicals is established. Hydroxyl radicals produced by Fenton reaction is trapped by spin trap reagent phenyl-t-butyl nitrone (PBN), and the free radical adduct of PBN can be detected by single sweep oscillopolarography, with its second order derivative cathodic wave at -0.52V vs SCE. The optimum experimental conditions for the determination is discussed, and the scavenging effects of some compounds on OH was also studied.
