>在硫酸亚铁-苯甲酸系统中也观察到了在将其他有机化合物引入到Sparkke剂量计中时观察到的Cl/sup -/和O/sub 2/的影响，尽管在这种情况下铁的产率比以前尝试的系统中的可再现性高得多，亚铁离子被苯甲酸溶液氧化，这一事实加强了过氧化物形成的结论，而苯甲酸溶液以前是辐射。苯甲酸的羟基异构体的生产被发现发生在更大程度上在这个系统（G = 1.9分子/100 ev; G/sub m/ = 3.1; G/sub p/ = 1.6）比在单独的苯甲酸的碱性溶液中的高，如Armstrong等人所研究的。（G/ sub o/ = 0.67 molecule/ev; G/sub m/ = 0.37; G/sub p/ = 0.37），并且与Armstrong（o/m/p = 9：5：5）或Loebl等人发现的比率不同，他们在pH值为3的条件下进行照射，得到的比例为5：2：10。这些差异可能表明分析技术的差异或由于亚铁离子的存在而导致的机理的根本差异。（auth）
>The effects of Cl/sup -/ and O/sub 2/ 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; G/sub m/ = 3.1; G/sub p/ = 1.6) than in alkaline solution of benzoic acid alone as investigated by Armstrong et al. (G/ sub o/ = 0.67 molecule/ev; G/sub m/ = 0.37; G/sub p/ == 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. (auth)
