Abstract
The main source of information on mechanisms for the formation of H/sub 2/O/sub 2/ and other molecular water radiolysis products is the dependence of their yields on the concentration of a substance (S) dissolved in the water. A diffusion/recombination model for water radiolysis predicts that at low (less than or equal to0.1 mole/dm/sup 3/) concentrations of S in water (C/sub S/) the yields of molecular water radiolysis products (G/sub M/), i.e., H/sub 2/ and H/sub 2/O/sub 2/, drop linearly with the cube root of C/sub S/. This paper attempts to prove the assumption experimentally by studying how G/sub H/sub 2/O/sub 2//, the ideal water breakdown yield, is affected by high concentrations of ethylene glycol in deaerated aqueous solutions. The observed radiolytic yield of H/sub 2/O/sub 2/ in this system agreed with the initial G/sub H/sub 2/O/sub 2//.
