Highly toxic o-toluidine pollutant was photo-degraded in aqueous media, under UV/solar light, by using commercial pure and Bi-doped ZnO and Bi2O3 nanopowders synthesized by precipitating method (with the addition of a dispersing agent). All the synthesized nanopowders were deeply characterized on structural, morphological, surface and optical points of view. For all the tests, the disappearance and the relative mineralization of o-toluidine molecules were followed by Linear Sweep Voltammetries (LSVs) and TOC determinations, respectively.

Abstract
Highly toxic o-toluidine pollutant was photo-degraded in aqueous media, under UV/solar light, by using commercial pure and Bi-doped ZnO and Bi2O3 nanopowders synthesized by precipitating method (with the addition of a dispersing agent). All the synthesized nanopowders were deeply characterized on structural, morphological, surface and optical points of view. For all the tests, the disappearance and the relative mineralization of o-toluidine molecules were followed by Linear Sweep Voltammetries (LSVs) and TOC determinations, respectively. Hence, correlations between their properties and the photocatalytic performances were drawn.
