New adsorbent based on polyaniline with chitosan were utilized for removal of Acetaminophen (AAP). The structure of these materials was studied by surface area, XPS, TPD, XRD, FTIR, TGA and SEM analysis. The higher adsorption rate of 385.25 mg.g(-1) for PANI@CS was obtained at contact time of 360 min and pH 7.0. Obtained results showed that removal of AAP was best fit by the pseudo-second-order and Langmuir adsorption models. Thermodynamic parameters of adsorption process of AAP showed the endothermic and spontaneous processes. Moreover, when reused, the hybrid adsorbent remains at around 69% of their original capacities after five adsorption cycles.
