| 摘 要： | 随着高级氧化技术成为废水处理的研究热点,羟基自由基的产生、测定及测定条件等相关问题的探索,成为发展高级氧化技术的重要条件及其重要组成部分。以分光光度法为主要分析方法,以二甲亚砜作为·OH的探针试剂,对Fenton反应及其反应的最佳条件进行研究。结果表明,在实验条件下,H2O2初始浓度为11.5mmol/L,Fe2+/H2O2的浓度比值在1:23左右,pH范围为3～4时,·OH产率最高。

| Abstract: | Along with advanced oxidation processes become the hot spots in the field of wastewater treatment,the production and determination of hydroxyl radical have been more important.This test,which studies the best Fenton reaction condition by spectrophotometry,testifies that·OH has its highest production rate when the H2O2 concentration is at 11.5mmol/L,Fe2+/ H2O2 is at 1:23 and pH is at 3～4. |
