Research on the ORP Indicating the Fenton Reation Process

摘要/Abstract

摘要:

采用Fenton氧化法处理模拟苯酚废水,研究了氧化还原电位(ORP)与H2O2投加量、H2O2/Fe2+投加摩尔比和pH等因素的变化,得出最佳控制条件:pH=3,n(H2O2)/n(Fe2+)=10,n(H2O2)=15mmol/L.实验发现,pH对Fenton体系中ORP整体变化趋势影响不大,当pH=3~6时,体系中ORP可达到500mV以上;H2O2投加量越高,所对应的ORP峰值出现越迟.通过对ORP变化规律的研究,为建立ORP控制Fenton氧化反应系统提供基础.

Abstract:

Phenol wastewater was treated by fenton oxidation to study the relationship between the oxidation-reduction potential (ORP) and main factors,such as the dosage of hydrogen peroxide,the mole ratio of hydrogen peroxide and ferrous ion and pH values.The optimum conditions were found:pH=3,n(H2O2)=15mmol/L,n(H2O2)/n(Fe2+)=10.Then,with the change of main factors,the experiment find that the influence of pH on ORP variation is not obivious.When pH=3~6,the ORP of system can reach 500mV above.On the other hand,with the increase of H2O2 dosage,the peak of ORP would be delayed.The study provides a basis for the establishment of ORP indicating the reation process.
