Abstract
The effects of solids on the decomposition of CCl/sub 4/ in water (with the ratio 1: 2) were studied with carbolen, silicagel, Al/sub 2/O/sub 3/, Fe/sub 2/O/sub 3/, and Cu/sub 2/O (varying from 1. 4 to 20 wt.%) exposed to gamma radiation from Co/sup 60/ to a dose of 4 x 10/sup 16/ ev/sec at 8 to 10 deg C. The plotted curves show an increase of Cl/sup -/ ion concentration with the presence of 1.4% of silicagel and a continuous (not proportional) increase of Cl/ sup -/ ions with the increase of silicagel concentrations. The ability of other solids to increase the ion yield is exhibited in the following sequence: Al/sub 2/ O/sub 3/) SiO/sub 2/> Fe/sub 2/O/sub coal> Cu/sub 2/O. It was found that oxygen does not participate in CCl/sub 4/ dissociation. The data indicate that the presence of oxygen and solid catalyst is necessary for increased radiolysis yield. (R.V.J.)
