The Radiation Chemistry of Aqueous Ferrous Sulfate-Benzoic Acid Solutions
The effects of Cl- and O2 observed when other organic compounds were introduced into the Fricke dosimeter were also observed with a ferrous sulfate-benzoic acid system, although ferric yield was considerably more reproducible in this case than in previously tried systems, The conclusion that peroxides are formed was reinforced by the fact that ferrous ion is oxidized by benzoic acid solutions which have previously been irradiated. The production of hydroxy isomers of benzoic acid was found to occur to a greater extent in this system (G = 1.9 molecules per 100 ev; Gm = 3.1; Gp = 1.6) than in alkaline solution of benzoic acid alone as investigated by Armstrong et al. (Go = 0.67 molecule/ev; Gm = 0.37; Gp == 0.37), and in different ratios from those found by Armstrong (o/m/p = 9: 5: 5) or by Loebl et al., who irradiated at pH 3 and got ratios of 5: 2: 10. These discrepancies might indicate either differences in analytic technique or a fundamental difference in mechanism due to the presence of ferrous ion.
