Figure 4

(a) Methylene blue degradation kinetics expressed as ratio between actual (c) and starting concentration (\(c_0\)) versus time on neat and \(\hbox {TiO}_2\)-coated FTO glass slides with and without 369 nm irradiation. Data points indicate the mean of three measurements and error bars denote the standard error of the mean. (b) Bacterial inactivation kinetics expressed as logarithm of survival rates versus time on neat and \(\hbox {TiO}_2\)-coated FTO glass slides with and without UV-A irradiation. The data point of the \(\hbox {TiO}_2\) 500 \(^{\circ }\hbox {C}\) with UV sample at 90 minutes cannnot be shown in the logarithmic presentation since the survival rate approached zero. The drawn lines serve as guide to the eyes.
