Photocatalytic elimination of E. coli over Au-TiO2 and Pt-TiO2.
Study of the effect of light intensity over the photocatalytic treatment.
The presence of the noble metal enhances the removal efficiency of E. coli.
2 wt.% Pt-TiO2 leads to obtain the total elimination of E. coli and other coliforms.
The photoreaction time was significantly reduced by using 2 wt.% Pt-TiO2.
