A one-step synthesis of 4-hydroperoxyifosfamide and 4hydroperoxytrofosfamide is described. The method involves direct ozonation of ifosfamide and trofosfamide and offers improved yields in comparison with Fenton oxidation and greater convenience in comparison with ozonation of the appropriate 3-butenyl phosphorodiamidate. Evaluation of the 4-hydroperoxy derivatives of cyclophosphamide, ifosfami...

In erythrocytes, auto-oxidation of oxyhemoglobine into methemoglobine, interaction of hemoglobine with redox drogs and ksenobiotics, Fenton and Haber-Weiss reactions catalyzed with metal (Fe) are factors that may lead to free radical production (2). Bounddissociation energies of alillic hydrogenes found in the structure of phospholipids in erythrocyte membranes are quite low. Therefore, polyuns...

Abstract Innovations in water technology are needed to solve challenges of climate change, resource shortages, emerging contaminants, urbanization, sustainable development and demographic changes. In particular, conventional techniques wastewater treatment limited by the presence poorly biodegradable organic matter. Alternatively, recent Fenton, Fenton-like hybrid processes appear successful fo...

The oxidation of aqueous solutions carbamazepine is conducted using the Fenton reagent, combined with photolytic action a 150 W medium pressure UV lamp, operating at T = 40 °C. effect acidity analysed an interval pH 2.0–5.0, verifying that 5.0 promotes colour formation (Colour 0.15 AU). iron studied, finding water increases in linear way, Colour 0.05 + 0.0075 [Fe]0. oxidising hydrogen peroxide ...

• Localized corrosion of stainless steel alloys in wastewater treated with an AOP. Dissolved ozone does not result increased pitting susceptibility. Pitting the studied lean duplex is induced by Fenton reagents. Crevice observed both and The examined when applied as a construction material advanced oxidation processes. Both electrochemical immersion experiments have been carried out subjecting ...
