Evaluation of the Aqueous Fe (II) ion Sorption Capacity of Functionalized Microcrystalline Cellulose

摘要: Abstract The absence of relevant functional groups, especially the oxygen-based have been reported to strongly limit metal binding capacity native cellulose. Therefore, this study successfully introduced substantive oxygenous groups (C=O, –OH, C–O, etc) onto microcrystalline cellulose via functionalization with 1,2,3,4-Butanetetracarboxylic acid. synthesized adsorbent (‘FM-cell’) was further utilised for aqueous iron (II) ion uptake. adsorbent’s instrumental characterization (scanning electron microscopy, SEM; Energy dispersion X-ray, EDX; X-ray diffraction, XRD and Fourier-transform infrared spectroscopy, FTIR) result confirmed presence their relative structural crystallinity. Similarly, effect process variable on ‘FM-cell’ adsorption elucidated batch mode. Dubinin-Radushkevich intraparticle diffusion models satisfactorily predicted isotherm kinetic data, respectively. sorption mechanism postulated strong adsorbent-adsorbate electrostatic interaction occasioned by large coordination number Fe ions. Thus, surface abundance significantly enhanced ‘FM-cell’.
