Synthesis and characterization of polyaniline-based biocomposites and their application for effective removal of Orange G dye using adsorption in dynamic regime

A polyaniline-modified almond ([email protected]) and walnut shells ([email protected]) biocomposites were designed and prepared via the in situ chemical polymerization in this investigation. SEM-EDX, FT-IR, and potentiometric titration were combined to analyze the texture and chemical structure of the as-synthetized [email protected] and [email protected] biocomposites. A dynamic adsorption process was employed to test the as-prepared biocomposite adsorbent performance to adsorb Orange G (OG) dye from effluents. The phenomenon of adsorption of OG on the as-prepared biocomposites has been found dependent on various operating conditions. Hence, this finding disclosed the suitable capability employment of [email protected] and [email protected] biocomposites for treating wastewater.
