摘要

采用实验方法研究了低成本环境友好型添加剂抗坏血酸(AA)对Fe2+/H2O2体系氧化NO气体及其对体系内H2O2分解的影响

分析了AA对体系氧化NO能力及H2O2分解的影响机制。研究结果表明:AA通过加速Fe3+向Fe2+的转化而促进Fe2+/H2O2体系对NO的氧化。[AA]0:[Fe2+]0对体系氧化NO的能力及H2O2的分解具有重要影响。综合考虑NO氧化脱除量及H2O2消耗量

合理的[AA]0:[Fe2+]0为1/3~1/2。AA的分次添加方式可大幅度提升体系氧化NO气体的能力。研究结果可望为发展基于H2O2为氧化剂的烟气NO绿色氧化技术提供理论基础。

Abstract

The influences of ascorbic acid (AA)

which is a low cost and eco-friendly additive agent

on NO oxidation and H2O2 decomposition in Fe2+/H2O2 system were experimentally studied and their reaction mechanisms analyzed. The results demonstrated that AA can improve oxidation of Fe2+/H2O2 system for NO through accelerating the reduction from Fe3+ to Fe2+. [AA]0:[Fe2+]0 ratio has important effect on oxidization ability and H2O2 decomposition of the system. Taken together the amounts of NO oxidized and H2O2 decomposition

the appropriate ratio of [AA]0:[Fe2+]0 should be between 1/3 to 1/2. Batch add of AA can greatly enhance the oxidation ability of Fe2+/H2O2 system for NO. These results would be a theoretical basis for the development of NO oxidation technology by H2O2.
