Adsorption Kinetics and Equilibrium of Cu(II) from Aqueous Solution by Polyaniline/Coconut Shell–Activated Carbon Composites
Publication: Journal of Environmental Engineering
Volume 139, Issue 10
Abstract
Polyaniline/coconut shell–activated carbon (PANI/GAC) composites were fabricated by chemical oxidative polymerization of aniline monomers with GAC as the supporting materials. These prepared PANI/GAC composites were characterized by scanning electron microscopy, adsorption-desorption analysis, and Fourier transform infrared spectroscopy. The effects of various parameters, including aqueous pH, contact time, the initial concentration of Cu(II), and temperature (288–323 K) on the Cu(II)’s adsorption, were investigated in detail. Results showed that the adsorption maximum occurs at around pH 5.5 and adsorption equilibrium was achieved in 90 min at Cu(II) concentration. The adsorption process followed the pseudo second-order kinetics, and the adsorption equilibrium data fit well with the Langmuir isotherm. Thermodynamic parameters indicated that the adsorption processes were endothermic, spontaneous, and more favorable at a higher temperature.
