Abstract
This study primarily involved the photocatalytic oxidation of caramelized sugar solution using immobilized titanium dioxide in fly ash-cement concrete slab under UV light. Percent caramel concentration reduction was the only parameter analyzed under room temperature and atmospheric pressure. One-way Analysis of Variance of 95% confidence level showed that there was significant difference between catalyst loading and fly ash-cement ratio with respect to caramel concentration. Titanium dioxide loading of 30% 9w/w) with 1:1 fly ash-cement ratio exhibited the highest photocatalytic capacity of the immobilized media was measured as 81.855 reduction after 24 hours of contact time. The semi-0batch flow kinetics followed first-order reaction with rate constant equal to 0.0033 per minute.
