O3/H2O2 treatment of methyl-tert-butyl ether (MTBE) in contaminated waters

MTBE in Drinking Water Production - Occurrence and Efficiency of Treatment Technologies

“…The method was adapted using a Tekmar 3000 purge & trap concentrator with an autosampler Precept II and a VARIAN 3400 gas chromatograph equipped with an ion-trap mass spectrometer ITS 40. Technical details of the analytical method are described elsewhere [17,18].…”

Photochemical treatment of phenol aqueous solutions using ultraviolet radiation and hydrogen peroxide

“…In the first step, hydrogen peroxide absorbs UV light and decomposes to highly reactive hydroxyl radicals ( • OH). Then, hydroxyl radicals, which are non-selective powerful oxidants, react with most organic compounds with very high rate constants (K ∼ 10 6 -10 10 M −1 s −1 ) [6][7][8]. They can abstract an H-atom from many sites of an organic molecule or add to any C C bond or accept an electron, producing therefore a wide spectrum of products [9].…”

Treatment of amoxicillin by O 3 /Fenton process in a rotating packed bed

“…The synergic mechanism is shown by Eqs. (1)e(12) (Benitez et al, 2009;Kang et al, 2002;Løgager et al, 1992;Safarzadeh-Amiri, 2001;Stefan et al, 2000). Abu Amr and Aziz (2012) treated stabilized leachate by using the O 3 /Fenton process and found that the degradation efficiency increased while O 3 consumption decreased (0.63 kg O 3 /kg COD) by the addition of Fenton into the ozonation process.…”
