title: Magnetic cellulose ionomer/layered double hydroxide: An efficient anion exchange platform with enhanced diclofenac adsorption property.
abstract: Polymeric ionomers with anion exchange capability are considered to be classes of environmentally friendly compounds as combination of them with anionic layered hydroxides constitute emerging advance materials. Biosorption by polymeric ionomer - layered double hydroxide (LDH) hybrid material exhibits an attractive green, low cost and low toxic - clean way. As a result, a novel anion exchange platform has been developed by the reaction of CaAl - LDH with Fe2+, cellulose solution, epichlorohydrin and pyridine. Magnetite cellulose - LDH (MCL) and the ionomer were used for efficient biosorption of diclofenac sodium (DF). Results showed that ionomer has more efficiency for DF adsorption relative to MCL. Magnetite ionomer showed fast equilibrium time (2min) with maximum uptake of 268mgg-1. Isotherm and Kinetic models were also studied. Regeneration of the sorbent was performed with a mixture of methanol -NaOH (2.0molL-1) solution.
