Kinetics Adsorption of Silver Ion by Blend Chitosan-Polyvinyl Alcohol Resin

Abstract—Blend chitosan-polyvinyl alcohol resin as adsorbent of silver ion was studied. Batch kinetic experiments were carried out the dosage of adsorbent between 0.1–0.5 g and initial concentration of silver ion in range 20.0–100.0 mg/L. The experimental result showed that an increasing dosage of adsorbent and initial concentration of silver ion increased percent adsorption and adsorption capacity. The adsorption capacity of blend chitosan-polyvinyl alcohol resin at 0.5 g and 100 mg/L was 19.1 mg/g. The pseudo-first order and pseudo-second order were employed to evaluate the kinetic model. It was found that the pseudo-second order model was fit for describing the adsorption behavior. The mechanism of silver ion adsorption onto blend chitosan-polyvinyl alcohol resin occurred in 3 steps. The rate limiting step for mechanism of adsorption was film diffusion.

Index Terms—Adsorption, chitosan-polyvinby alcohol, kinetics, silver ion.
