Abstract

Abstract: We report herein the synthesis of chitosan‐polyaniline/Fe3 O4 (CS‐PANI/Fe3 O4 ) nanocomposite for decoloring of Reactive Red 198 (RR 198) in aqueous solution. The prepared CS‐PANI/Fe3 O4 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‐PANI/Fe3 O4 in 50 mL of 50 ppm RR 198 dye solution, pH of 7 and adsorbed time of 120 min. The results indicated that the removal percentage of RR 198 dye was increased and up to 96.16 % when the adsorbed times increased.
