The removal of pharmaceuticals from the potable water supply is an issue that impacts all humans. Research that identifies the most effective and lowest-energy methods to purify water is of critical significance. 15nm diameter Titanium dioxide nanoparticles (TiO2 NPs) were used as a medium to filter aqueous 5.0ppm caffeine solution, and the filtered samples were analyzed via UV-Vis spectrophotometer. The results showed a decrease in absorbance at 273nm (caffeine peak) when compared to the 5.0ppm standard solution, suggesting that the TiO2 NPs were successful at removing some of the caffeine from the water samples. Future research will focus on the ability of TiO2 NPs to react with other organic molecules, and detecting through which specific functional groups interaction occurs.
