Electrocatalytic oxidation of arsenic coupled with liquid-phase polymer-based retention : analysis and extraction of trace arsenic
type: Dataset
description: This work deals with the electrochemical synthesis and structural characterisation of composite nano-structured functionalized polymer electrodes containing a homogeneous dispersion of ruthenium oxide or iridium oxide nanoparticles, and the study of their electrocatalytic properties towards arsenic (III) oxidation to arsenic (V) in aqueous medium. The combination of electrocatalytic oxidation of arsenic (III) with the ultrafiltration technique LPR (Liquid Phase Polymer-assisted Retention) allowed us to confirm the usefulness of this combined approach for arsenic removal. In this process, the nanocomposite materials based on iridium oxide showed the most interesting properties because they are capable of catalyzing the oxidation of arsenite in neutral and slightly positive potential. Finally, the iridium oxide nanostructured electrodes are also effective for the catalytic water oxidation of 4-electrons in oxygen and thus have the potential to be used in the context of the dissociation reaction of water. Keywords: ruthenium oxide, iridium oxide, nanocomposite, electrocatalysis, arsenic, ultrafiltration, water oxidation.
