Fenton reaction

This post was last edited by zdl1966 on 2016-10-21 at 14:07. In inorganic chemical reactions, a mixture of hydrogen peroxide (H2O2) and ferrous ions (Fe) is used to oxidize many known organic compounds such as carboxylic acids, alcohols, and esters into inorganic forms. This reaction possesses a high capacity for removing refractory organic pollutants, and it is widely used in the treatment of various types of wastewater, including printing and dyeing wastewater, oily wastewater, phenol-containing wastewater, coking wastewater, ***-containing wastewater, and diphenylamine wastewater. Fe2+ + H2O2 → Fe3+ + OH- + ·OH ① H2O2 + Fe3+ → Fe2+ + O2 + 2H+ ② O2 + Fe3+ → Fe2+ + O2· ③ It can be seen that in the Fenton reagent, in addition to the formation of 1 mole of OH· radicals, 1 mole of peroxide radical O2· is also produced. However, the oxidation potential of the peroxide radical is only around 1.3 V; therefore, it is the OH· radicals that play the main role in oxidation within the Fenton reagent.

It is mainly the oxidative action of hydroxyl radicals. It is a reducing substance in the oxidized water formed by ferrous ions and hydrogen peroxide at a pH value of less than 4.0; the specific dosage requires extensive pilot testing.

What do you want to ask? Is it regarding the treatment of a specific type or category of water, or the basic principles? The basic principles were explained in detail on the second floor. If it’s about a particular type of water and a Fenton test is needed, it’s also necessary to know the quality of that water as well as the requirements for the treated water

Based on the fundamental principles, Fenton needs to conduct more experiments in order to obtain targeted results

The pH is around 3.0; I’ve conducted many experiments and find the results to be average.
