Abstract

The simuated caramelized sugar solution of three different concentrations was treated by photocatalytic oxidation of pelletized titanium dioxide (TiO2) to determine the effect of the initial concentration of wastewater to the percent concentration reduction and to determine the applicability of the set up to the color removal of the wastewater. The percent concentration reduction of the concentrations 62.5 g/L 37.5 g/L and 25 g/L were 43.18, 49.11 and 53.14, respectively, which shows that the lower the initial concentration the higher the percent concentration reduction. Also, percent reduction by using pelletized TiO2 was compared to the percent reduction using suspended TiO2 with constant TiO2 loading, pH, and volume of solution. It was then found out that the percent reduction in suspended TiO2 exposed to UV light was 92.8 while 44.04 for the one not exposed to any light source. The photodegradation of caramel concentration by UV light was 42.12. The photocatalytic oxdation of TiO2 based from the previous studies was a first order reaction. The rate constant, k was the slope of the line ln(C/Co) versus time. The rate constant computed for 62.5 g/L, 37.5 g/L and 25 g/L were 0.1217/hr, 0.1057/hr, and 0.0361/hr, respectively.
