Abstract: | We report here in the synthesis of chitosan-polyaniline/Fe₃O₄ (CS-PANI/Fe₃O₄ nanocomposite for decoloring of Reactive Red 198 (RR 198) in aqueous solution. The prepared CS-PANI/Fe₃O₄ was characterized by using Fourier transform infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FE-SEM), and X-ray diffraction (XRD). Various factors affected the removal of RR 198 such as removal time, dye concentration, pH, and adsorbent dose were also investigated. The maximum removal yield was found to be 96.16 % when adsorbed condition was 0.1 g of CS-PANl/Fe₃O₄ in 50 mL of 50 ppm RR 198 dye solution, pH of 7 and adsorbed time of 120 min. The results indicated that the rcmoval percentagc of RR 198 dye was increased and up to 96.16 % when the adsorbed times increased. |
