Abstract
In this study, we investigated the decomposition of highly concentrated hydrogen peroxide in the range of 1.04-2.55 M by transition metal ion catalysts such as $Fe^{2+}$ and $Cu^{2+}$. The effect of metal ion concentration on the decomposition of hydrogen peroxide was examined experimentally, and the decomposition rate constants were determined by combining the experimental data with a theoretical approach. The rate of the decomposition of hydrogen peroxide was found to be first order with respect to its concentration. The decomposition rate constant was able to be treated as a linear function of the initial metal ion concentration. The validity of the decomposition rate constants determined was verified by good agreements between the calculated and experimental results.
