Özet
The removal of organic dyes from aqueous media is a significant effort for environmental protection. Among various treatment methods, heterogeneous photocatalysis is a promising advanced oxidation process to eliminate the organic effluent dyes. This method is based on the usage of UV-A light and a semiconductor simultaneously. MgO is a favorable photocatalyst due to its advantages such as being environmentally friendly, cost-effective, and having high chemical stability. The present work was focused on the determination of photocatalytic degradation of two different dyes categorized according to their chromophores under UV light. Methylene blue (MB) and Reactive Blue 19 (RB-19) were used as thiazine and anthraquinone model dye compounds, respectively. The structural changes in the functional groups of dyes with the presence of MgO involved in the photocatalytic process have been assessed by using ATR-FTIR. The photocatalytic degradation kinetics of dyes were followed by UV–vis spectroscopy. A higher removal efficiency was obtained for the degradation of RB-19 dye compared to MB. Moreover, the effect of initial dye concentration on the degradation of dyes were studied. The maximum removal efficiencies for both dye solutions were obtained at 2.5 mg/L.
