dc.description.abstractThis study investigates As(V) removal from aqueous solutions using a novel amine-doped acrylic ion exchange fiber. The amine doping reaction was confirmed using FT-IR, and the surface of the fiber was characterized using FEG-SEM. The synthesis process was completed within 60 min using an AlCl3 center dot 6H(2)O catalyst at 100 degrees C, and the resulting in a fiber with an ion exchange capacity of 7.5 meq/g. The removal efficiency of the A-60 fiber was affected by the solution pH, and the efficiency was optimum at pH 3.04. As(V) adsorption on the fiber was rapid in the first 20 min and reached equilibrium in 60 min. As(V) removal followed pseudo-first-order kinetics, and the Redlich-Peterson adsorption isotherm model provided the best fit of the equilibrium data. The fiber has an As(V) adsorption capacity (q(e)) of 205.32 +/- 3.57 mg/g, which is considerably higher than literature values and commercial adsorbents. The removal efficiency of the fiber was above 83% of the initial value after nine regeneration cycles. (C) 2016 Elsevier B.V. All rights reserved.-
