The Effect of pH on the Radical Yields in the γ-Radiolysis of Aqueous Systems

Abstract

IT is customary to describe the state of affairs about 10−8 sec after the passage of a fast electron traversing a liquid aqueous medium by equation (1) : in which G‘H’ and GOH are the numbers of H atoms and OH radicals respectively which are available to react with solutes for each 100 eV energy deposited in the water. Recent work1,2 has shown that the precursor of the hydrogen atom is a solvated electron, eaq, capable of reaction in this form with solutes such as N2O3, ClCH2COOH4, O22, H2O22, etc. The solvated electron is also able to react with hydrogen ions according to equation (2), when it is converted into a hydrogen atom:
