Figure 12

Change in absorbance as a function of time on irradiation of an aqueous solution of Remazol Brilliant Blue R in the presence of Ce-doped TiO₂. Experimental conditions. Reaction vessel: immersion well photochemical reactor made up of Pyrex glass, light source: visible light halogen linear lamp (500 W, 9500 Lumens), photocatalyst: Ce-doped TiO₂ (1 g L⁻¹), dopant conc. (Ce) 9% (w/v), Dye (0.05 mM), volume (200 mL), continuous stirring, and air purging. Calcination temperature: 400°C, calcination time: 4 h, and irradiation time: 90 min.
