Basic Blue Dye Adsorption from Water using Polyaniline/Magnetite(Fe₃O₄) Composites: Kinetic and Thermodynamic Aspects.

ABSTRACT: Owing to its exciting physicochemical properties and doping-dedoping chemistry, polyaniline (PANI) has emerged as a potential adsorbent for removal of dyes and heavy metals from aqueous solution. Herein, we report on the synthesis of PANI composites with magnetic oxide (Fe₃O₄) for efficient removal of Basic Blue 3 (BB3) dye from aqueous solution. PANI, Fe₃O₄, and their composites were characterized with several techniques and subsequently applied for adsorption of BB3. Effect of contact time, initial concentration of dye, pH, and ionic strength on adsorption behavior were systematically investigated. The data obtained were fitted into Langmuir, Frundlich, Dubbanin-Rudiskavich (D-R), and Tempkin adsorption isotherm models for evaluation of adsorpt
