dc.description.abstract Tebuconazole, a widely used fungicide is toxic to the environment and has been reported as a water contaminant. In this study, the adsorption of aqueous solution tebuconazole onto faujasite X (NaX) was investigated in batch mode. Equilibrium sorption data at 303 K were analyzed using Langmuir, Freundlich, and Temkin isotherm models. The adsorption data was found to be described by the models in the order Langmuir> Freundlich> Temkin model. For the 293–323 K temperature range studied, the percent removal of the pesticide decreased with increase in temperature. The sorption process was found to follow the pseudo-second-order kinetic model while Intraparticle diffusion model indicated that the adsorption process was multi-mechanistic and pore diffusion was not the sole rate-controlling step. The calculated thermodynamic parameters∆ G,∆ H and∆ S for … en_US
