亚铁离子+过氧化氢体系的研究揭示了几个新的特征。一个一致的反应机制，涉及自由基HO和HO，已被提出。看来HO与过氧化氢的反应在该体系中不起作用。氧是通过HO与铁离子的反应而放出的。本文详细分析了Fe2 ++ H2O2体系在一定实验条件下的动力学和析氧数据，得到了Fe2+、Fe2+和Cu2+与H2O2自由基反应的速率常数比值。这些反应的pH依赖性似乎表明与铁和铜离子的反应通过阴离子0，“进行。
An investigation of the ferrous ion+ hydrogen peroxide system has revealed several new features. A consistent reaction mechanism involving the radicals HO and HO, has been proposed. It appears that tfie reaction of HO, with hydrogen peroxide, hitherto generally accepted, plays no part in this system. Oxygen is evolved by reaction of HO, with the ferric ion. Cupric ions have a pronounced effect on the system and this is interpreted in terms of the reaction scheme.A detailed analysis of kinetic and oxygen evolution data for the ferrous ion+ hydrogen peroxide system under certain experimental conditions, has led to values for the ratios of the velocity constants for the reactions of ferric, ferrous and cupric ions with the HO, radical. The pH dependence of these reactions seems to indicate that the reactions with ferric and cupric ions proceed through the anion 0,’.
