Fenton氧化降解活性艳红X-3B条件及历程研究
A Study of Degradation of Reactive Brilliant X-3B Based on Fenton Oxidation
摘要
Abstract
[ Objective] We aimed to study the degradation conditions and course of reactive brilliant X-3B on the basis of Fenton oxidation. [Method] By using Fenton oxidation,we studied the degradation conditions of reactive brilliant X-3B wastewater with different initial concentration, then analyzed its degradation products and process through gas chromatography-mass spectrometer (GC-MS). [Result] When H2O2: Fe2+ (molar ratio) =3.1 ,the removal rate of COD was the highest. With the increase of Fe2+ usage,the wastewater became red and more deposits generated. As COD of wastewater was 200,400 and 800 mg/L,the usage of H2O2 was 0.5,1.0 and 3.5 ml respectively, and the initial pH of the wastewater was 4 -5,the removal rate of COD reached the maximum values. In addition,Fenton action was very fast,that is,most degradation occurred in the first 5 min. [Conclusion] Fenton oxidation is practical and efficient in the degradation of dyes that are degraded difficultly.关键词
