<div> <p>MB decolarization with pure TiO<sub>2</sub> and Ag doped TiO<sub>2</sub> based photocatalytic system were investigated under UV-A and UV-Visible conditions. Different ratios of Ag were used as metal dopant. 1% Ag-TiO<sub>2</sub> increased the decolorization efficiencies of MB and MO dyes, also the k<sub>app</sub> constant enhanced under UV-A and UV-Visible conditions. A central composite analysis showed the effect of initial dye concentration, pH, Ag-TiO<sub>2</sub> concentration and the reaction time of photocatalytic process under UV-A irridation in both dyes. The photocatalytic degradation pathways of both dyes by Ag doped TiO<sub>2</sub> catalyst were obtained in this study. According to these results, the application of Ag-TiO<sub>2</sub> catalyst are proved to be more effective than pure TiO<sub>2</sub> catalyst for both MB and MO removal. The toxicity test of Daphnia Magna shows that non toxic wastewater discharge to the receiving environment could be possible with photocatalytic degration by Ag-TiO<sub>2</sub> catalyst.</p> </div> <p>&nbsp;</p>
