Abstract
Caffeine (CAF) is a widely used stimulant in beverages, foods, and drugs. Extreme usage of this popular molecule can create caffeine pollution for water sources. A photocatalytic method was developed to degrade CAF in water. The pillared interlayered clays (PILCs) were used as the photocatalytic material. Zeolite, a type of clay, was used to prepare PILCs. The operational parameters, such as reaction time, CAF concentrations, H2O2, and PILCs amounts, were examined to obtain the highest removal percentages. The removal rates reached 97%, 100%, and 100% in 120, 180, and 300 min, respectively, using 1.0 mL H2O2 and 1.0 g of Fe-Ti-PILC for 50.0 mg/L CAF under UV exposure. The experiments were carried out in batch method, and RP-HPLC was used to find the remaining CAF concentrations.
