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.

본 연구에서는 철$(Fe^{2+})$이나 구리$(Cu^{2+})$와 같은 전이 금속 이온 촉매에 의한 고농도(1.04-2.55 M) 과산화수소의 분해 거동에 대해 살펴보았다. 과산화수소의 분해에 미치는 금속 이온 농도의 영향이 실험적으로 조사되었고, 이로부터 얻어진 실험 데이터와 이론적 접근을 통해 과산화수소에 대한 분해속도상수가 결정되었다. 과산화수소의 분해 속도식은 과산화수소 농도 관점에서 1차인 것으로 나타났으며, 과산화수소 분해 속도 상수는 금속 이온 초기 농도의 선형 함수로 취급될 수 있었다. 본 연구에서 결정된 분해 속도 상수를 이용하여 계산한 결과는 실험적으로 얻어진 과산화수소 분해 데이터와 잘 일치하였다.
