Continuous H2O2 production sustained by anodic O2 for the destruction of the antibiotic ampicillin by photoelectro-Fenton process in a rotating cylinder electrode reactor

Autor: Oscar M. Cornejo, Ignasi Sirés, José L. Nava

Complete degradation of the antibiotic ampicillin (AMP) by photoelectro-Fenton (PEF) process has been addressed for the first time. Once produced from water oxidation at six Ti|IrO2 anodic plates, O2 was quickly transported by forced convection towar

Solar Photoelectro-Fenton-Like Process with Anodically-Generated HClO in a Flow Reactor: Norfloxacin as a Pollutant with a Particular Structure

Autor: María F. Murrieta, Enric Brillas, José L. Nava, Ignasi Sirés

Publikováno v: SSRN Electronic Journal.

The degradation and mineralization of the drug norfloxacin (NFX) has been assessed in a model solution, containing 15 mM NaCl +45 mM Na2SO4 at pH 3.0, using a flow plant with an FM01-LC filter-press reactor equipped with a Ti|Ir-Sn-Ru oxides anode to
