Fenton’s reagent is a mixture of hydrogen peroxide and iron that reacts with toxins in polluted water, transforming them into harmless compounds. It is commonly used to remove chemical wastes from water and improves its quality by removing discoloration and odors. The reagent works quickly and leaves little behind, but requires careful analysis to avoid accidental reactions.
Fenton’s reagent is a substance that contains hydrogen peroxide and iron. The mixture is highly reactive. It is added to polluted water, where it reacts with toxins, transforming them into harmless compounds or compounds that can be removed from the water. This allows people to reuse the water instead of forcing it to be stored until the toxins break down. The reagent is commonly used to remove chemical wastes, such as phenols, from water.
Hydrogen peroxide molecules are made up of two oxygen atoms and two hydrogen atoms. In solution, the molecules create hydroxide ions, which have one hydrogen atom and one oxygen atom. Hydroxide reacts easily with other molecules. When iron is added to a hydrogen peroxide solution, it facilitates the breakdown of hydrogen peroxide into hydroxide, making the solution even more reactive. The hydrogen peroxide solution is said to be catalyzed by iron and the combination is called Fenton’s reagent.
HJH Fenton, who gave Fenton’s reagent his name, discovered the potential of the mixture in 1894. At the time, however, the chemist community did not understand why the solution acted the way it did. Decades later, other scientists identified the process by which the solution cleaned the water. After that discovery in the 1930s, factories began using the reagent to clean up industrial waste.
The solution is capable of removing a variety of wastes from water, including several common industrial by-products. For example, it can break down phenols and other toxic organics. Increases wastewater quality, as measured by biochemical oxygen demand and chemical oxygen demand. The reagent also improves the aesthetic qualities of the water by removing discoloration and odors caused by pollutants.
The mechanism by which Fenton’s reagent works is general, which means that the treatment can be applied to a wide range of toxins and pollutants. This also means that the reagent does not discriminate between dissolved molecules in the wastewater. Hydroxide ions can react with molecules that the people who treat the water didn’t intend to change. The use of the reagent requires careful analysis to avoid accidental reactions.
In some cases, targeted treatment additives may be a better choice than Fenton’s reagent. However, it has distinct advantages. It works quickly compared to other solutions. The reagent also leaves little behind: unreacted hydrogen peroxide breaks down into oxygen and water, so the treatment causes no further problems in the water supply.
