Optical absorbance spectra, residue MB percentage, and survival ratio. (a) UV-visible light absorbance spectra of T0, T3, T4, and T5, compared with that of P25 TiO2 nanoparticles. (b) The residue MB percentage vs. treatment time in treated MB solutions by P25 TiO2 nanoparticles, the sample T0, and the sample T3 under visible-light illumination, respectively. (c) Survival ratio of E. coli cells vs. visible-light (λ > 400 nm) illumination time with T3, T0, P25, respectively.
