Abstract
Amitraz removal was investigated by synthesized TiO2 from an aqueous solution. For this propose, FT-IR, XRD, UV–Vis, SEM and EDS were used to characterize the synthesized nano adsorbents and to determine the removal process. Batch adsorption studies were conducted to investigate the effect of temperature, initial Amitraz concentration, adsorbent count and contact time as important adsorption parameters. The maximum equilibrium time was found to be 15 min with 5 mg adsorbent in 35ºC at pH=7 for TiO2. All the adsorption equilibrium data were well fitted to the Freundlich isotherm model with heterogenous, multilayer, temperature depended, irreversible and spontaneously behavior. The ∆H is -4.2×103 kJ and ∆S is 15 J mol-1K-1.
