A cost effective Graphene/TiO2 nanocomposite having photocatalytic properties has been prepared for the removal of aspirin from the aqueous solution. The quantity of TiO2 was varied (1:0.04, 1:0.1, and 1: 0.2 GO-TiO2) in the composite and effect on adsorption as well as photo degradation efficiency was observed. The 1:0.1 GO-TiO2 composite has been found to be best one for aspirin degradation, confirmed by pseudo first order rate constant i.e. 0.006 min-1. By performing kinetic experiments, the pseudo-first-order kinetic model provided the best fit for TMP adsorption onto GO-TiO2 Nano composite. The influence of various parameters, namely pH (3-11) initial concentration (8, 17, 30 ppm), dose (5 – 150mg) on the removal efficiency of TMP by the composite has been analyzed. The characteristics of GO-TiO2 nanocomposite were analyzed using AFM, FT-IR, analysis. The maximum TMP removal efficiency was found to be 39% for pure TiO2, 83% for GO, and 96% for 100mg of 1:0.1 G0-TiO2 nanocomposite for 30 ppm aspirin solution.
