WebFenton reaction can also involve several other cations of metals (M n+), the processes connected with the reactions similar to Fenton reaction may be characterized as follows [33]:
WebThe Fenton reagent is the combination of ferrous ion (Fe++) with H 2 O 2 participating in chemical reactions ( Schrank et al., 2005 ). This reagent act as a catalyser which increases the rate of OH° generation. The Fenton’s oxidation process is a pH adjustment, oxidation reaction, neutralization and coagulation for precipitation. WebJun 5, 2024 · Laboratory exercise is an essential part of this course. The goal of this laboratory exercise is to demonstrate the possibility of using an in-situ spectroscopic method (UV-VIS spectroscopy) to investigate reaction kinetics. A solution of naphthol blue black (NBB) is oxidized by H 2 O 2 through a Fenton oxidation process.

Fenton's reagent is a solution of hydrogen peroxide (H2O2) with ferrous iron (typically iron(II) sulfate, FeSO4) as a catalyst that is used to oxidize contaminants or waste waters as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene (TCE) and tetrachloroethylene (perchloroethylene, PCE). It was developed in the 1890s by Henry John Horstman Fenton as an analytical reagent.
