We studied the reaction between hypochlorite anion (OCl) and hydrogen peroxide (H2O2) by using spin-trapping agents such as 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) and 5- diethoxy-phosphoryl-5-methyl-1-pyrroline-N-oxide (DEPMPO). The obtained data demonstrate that hydroxyl radical is produced in this reaction. Thus, OCl and H2O2 could assume new relevance in environmental chemistry by representing a potential source of hydroxyl radicals and other oxidant species, such as HO–OCl and OCl radical.

Abstract

We studied the reaction between hypochlorite anion (OCl) and hydrogen peroxide (H2O2) by using spin-trapping agents such as 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) and 5- diethoxy-phosphoryl-5-methyl-1-pyrroline-N-oxide (DEPMPO). The obtained data demonstrate that hydroxyl radical is produced in this reaction. Thus, OCl and H2O2 could assume new relevance in environmental chemistry by representing a potential source of hydroxyl radicals and other oxidant species, such as HO–OCl and OCl radical.
