Title: Determination of oxidation products in radiolysis of halophenols with pulse radiolysis, hplc, and ion chromatography

Abstract

This paper reports on hydroxyl radicals that react with halogen substituted phenols by several different ways. One is addition of OH radicals to the aromatic ring, which is followed by elimination of hydrogen halide, H{sub 2}O or H{sup {minus}}. The positions of OH radicals attack are dependent on the nature of the halogen which affects the electronic distribution in the ring. The oxidation of fluorophenols, chlorophenols and bromophenols with hydroxyl radicals in N{sub 2}O saturated solution has been investigated with pulse radiolysis and {gamma}-irradiation experiments. The intermediates of the reactions were studied by pulse radiolysis. The products created in the {gamma}-irradiation of aqueous solutions of halophenols were analyzed by ion chromatography and high performance liquid chromatography (HPLC). With the combination of time-resolved and steady-state experiments a complete and detailed description of radiolytic oxidation of halophenols by hydroxyl radicals was obtained.
