TL;DR: In this paper, results on As(V) removal in the presence of oxygen using the zerovalent iron technology with commercial iron nanoparticles (NanoFe ® ) are presented, showing the effect of nanoFe ® mass, UV light and addition of humic acids.

TL;DR: Although reduction to solid As(0) is convenient for purposes of As removal from water as a deposit on TiO(2), attention must be paid to formation of AsH(3), one of the most toxic forms of As, and strategies for AsH (3) treatment should be considered.

TL;DR: In this article, the photocatalytic activity of supported TiO 2 to potabilize water in common plastic PET bottles under solar irradiation was evaluated using model compounds as 4-chlorophenol and 2,4-dichlorophenoxyacetic acid.

TL;DR: UV irradiation of an ethanolic sol of TiO2 nanoparticles produces a trapped Ti(III) centre and a noticeable Burstein shift, suggesting that accumulated charges can drive the otherwise forbidden reduction of As(V) by conduction band electrons.

TL;DR: In this article , composite films based on dispersions of bismuth ferrite (BiFeO3) in polyvinylidene fluoride (PVDF) matrixes were prepared in the presence of multiwalled carbon-nanotubes (MWCNT), using xanthan gum (XG) as dispersant.
