Abstract
A novel adsorbent, NC-PEG, obtained by modification of nanocellulose (NC) with PEG-6-arm amino polyethylene glycol (PEG-NH2) via maleic anhydride (MA) linker, was used for removal of Cd2+ and Ni2+ from water. A subsequent precipitation of iron oxide (FO) from goethite on NC-PEG was employed to produce NC-PEG/FO adsorbent which was used for As(V) and As(III) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on the adsorption efficiency were studied. The maximum adsorption capacities found for Cd2+ and Ni2+, obtained by the use of Langmuir model, were 37.9 and 32.4 mg g(-1) at 25 degrees C, respectively. Also, high As(V) and As(III) removal capacities of 26.0 and 23.6 mg g(-1) were obtained. The thermodynamic parameters indicated endothermic, feasible and spontaneous nature of the adsorption process. The kinetic study, i.e., fitting by Weber-Morris model predicted that intra-particle diffusion was the rate-controlling step. The ability... for multi-cycle reusability of both NC-PEG and NCPEG/FO, represents a positive indicator when considering their possible applications.
