A novel CoFe2O4/chitosan magnetic composite, where CoFe2O4 is known as cobalt ferrite, was synthetized, characterized and applied to adsorb indigotine blue dye (IBD). According to the central composite design (CCD), adsorption of IBD onto CoFe2O4/chitosan composite was favored when initial pH and adsorbent dosage were 3.0 and 0.75 g L–1, respectively. Adsorption was a fast process, well represented by pseudo–first order model, being the equilibrium reached at 15 min. Concerning the equilibrium behavior, the adsorption was satisfactorily modeled by the Langmuir model, reaching maximum adsorption capacity of 380.88 mg g–1 at 328 K. The thermodynamic parameters indicated a spontaneous, favorable and endothermic adsorption process. CoFe2O4/chitosan magnetic composite is an efficient adsorbent to remove dyes from aqueous media, presenting advantages like fast kinetic, high adsorption capacity and interesting magnetic properties that allows the easy separation after the adsorption operation.
