Removal of As Using Chitosan–Montmorillonite Composite: Sorptive Equilibrium and Kinetics
Published 2013-04-01“…The adsorption kinetics demonstrated intra-particle diffusion as the rate-determining step during the initial phase of adsorption (up to 10 minutes of contact time), which were supported by X-ray diffraction studies; by contrast, chemisorption was found to be the rate-determining step during the later part of adsorption (after 10 minutes of contact time), which were confirmed by Fourier transform infrared spectroscopy-attenuated total reflectance studies. Desorption of As 3+ from the sorbents was optimized using potassium dihydrogen phosphate, wherein 0.1 M of the desorbate was found to be an appreciable regenerating agent supporting the reusability of the sorbent up to three cycles, retaining 4402 μg g −1 of the metal ion.…”
