Fe2+/H2O2体系O2生成路径
O2 generation path in Fe2+/H2O2 system
摘要
Abstract
It is important to understand the O2 generation path in Fe2+/H2O2 system to avoid invalid decomposition of H2O2 and to reduce the cost of pollutants degradation technology using Fe2+/H2O2 system. In this paper, radical scavengers were adopted to investigate the roles of different radicals on the generation of O2 in Fe2+/H2O2 system. The results showed that there were fewO2−i in Fe2+/H2O2 system, and2O−i was not the main reagent to generate O2. AfteriOH was captured, the generation rate of2HOi was still high, however, there was no O2 generation. This indicated thati OH and2HOi took part in the reaction to generate O2 directly.i OH+2HOiH2O+O2 is the main reaction path to generate O2. Controling H2O2 decomposition path towardsi OH and restraining the production of2HOi were the effective ways to increase the utilization rate of H2O2.关键词
