When supercoiled pBR322 plasmid DNA (form I) was exposed to
Fenton's reagent (FeS[O.sub.4] and [H.sub.2][O.sub.2]), form I converted to nicked pBR322 plasmid DNA (form II) by single-strand breaks as shown in lane 2 in Figure 4.
Several researches [8-11] have been carried out to degrade the dyes photochemically using heterogeneous catalyst as cyclic ketones, and
Fenton's reagent [12] and different techniques such as fluorescence [13], cyclic voltammetry [8] and stopped flow spectroscopy [14] were used to investigate the reduction of dyes.
Fenton's reagent was used to test the disintegration quantity of [H.sub.2][O.sub.2] in the ceramic slurry [10].
Among the most promising AOPs for water contaminated by organic molecules are, application of the
Fenton's reagent (an aqueous mixture of Fe 2+ and H 2 O 2 that produces hydroxyl radicals OH .
Toxicity of industrial wastewater treated by
Fenton's Reagent. Polish Journal of Environmental Studies, 14: 11-16.
Among these AOTs,
Fenton's reagent is particularly gained attention because of its low cost, the lack: of toxicity of the reagents, and absence of a mass transfer limitation due to its simplicity of the technology and homogeneous catalytic nature (Liao et al.
A study investigating the sonoelectrochemical degradation of an organic compound employing
Fenton's reagent, Physical Chemistry, 4: 5340-5345.
The
Fenton's reagent consists in reaction between ions iron and hydrogen peroxide (HP), which generates hydroxyl and hydroperoxyl radicals with high oxidation-reduction potential (2.8 V vs.
Phenol removal from high salinity effluents using
Fenton's reagent and photo-Fenton reactions.
The oxidative stability of the membranes was tested by immersing the films into
Fenton's reagent (3% [H.sub.2][O.sub.2] containing 2 ppm FeS[O.sub.4]) at 80[degrees]C.
The typical oxidants used for ISCO are potassium permanganate, hydrogen peroxide (
Fenton's reagent), and ozone [4].
The ability of different concentrations of plant extract to protect pUC19 plasmid DNA from harmful effects of hydroxyl radicals produced by
Fenton's reagent was evaluated by DNA nicking assay as described earlier [28] with minor modifications.
