This research aims to examine the adsorption behavior of composite polymers (PAn- PET) (polyaniline with recycled polyethylene terephthalate (r-PET) were made from plastic bottles that had already been used, nanofibers adsorbing contaminants from a solution containing pesticides. XRD diffraction and SEM were used to characterize this nanofiber composite. Using batch adsorption studies, adsorption variables including contact time, starting pesticide dosage, and adsorbent dose were optimized. Under optimum conditions, the maximum removal efficiency was 81%. In addition, the three Langmuir, Freundlich and Temkin isothermal adsorption models were also applied and the Langmiur isothermal model (R2 = 0.9857) better described the adsorption equilibrium data. Using experimental data, the feasibility of recycled polyethylene terephthalate-recycled polyethylene terephthalate nanofibers in the removal of PCP indicates a promising option for the removal of pollutants from water.
