Pulse radiolysis study of I− oxidation with radical anions Cl2 ⋅− in an aqueous solution

Abstract

Radiation-chemical transformations of chloride solutions in the presence of iodide additives were studied by pulse radiolysis. Radical anion Cl2 ⋅− oxidize I− ion, while in the secondary reactions Cl2 reacts with I− to form a mixed trihalide ion ICl2 −. A reaction model that satisfactorily describes the experimental data was proposed.
