reaction(1.4) or (1.5)or reacts directly with a substrate also depends on the chelator as well as the nature of the substrate. So, in different circumstances, one or all three of the reactive species may be the oxidant in reaction(1.6). These species are difficult, if not impossible, ...
Control reactions using H 2O 2 without Fe 2+ were carried out, but DMDS degradation could only reach 60% for a 0.025 mg L 1 DMDS solution, at pH 3, 60 掳C using 10,000 mg L 1 H 2O 2 in 30 min of reaction. The Fenton's reaction could effectively remove DMDS, reaching 95% ...

There is something intriguing and at the same time fascinating that a simple reaction (of Fe 2+ ions with H 2O 2), which was observed by H.J.H. Fenton over 110 years ago, proves to be very difficult to describe and understand. As yet the nature of the oxidizing species obtained in...

This result implies that as is different from the decomposition under the fuel cell operation condition, the Fenton reaction simultaneously decomposes two C–F and one C–S bonds of Nafion membrane. The Fenton reaction mechanism has so far been discussed on the basis of the H2O2decomposition react...

The comparison of effectiveness as an iron source for Fenton's reaction was made among several kinds of iron and reticulated iron was chosen as the best material. While organic chlorine compounds added in pure water were easily decomposed by Fenton's reaction on porous (reticulated) iron in ...
However, a TPH reduction of 43.1% was observed for the combined process of ultrasound and Fenton's reaction, indicating that the individual AOP is complementary to one another. As a result, the combined process could be acted as a more effective method to treat oily sludge as compared to ...
