Kinetics and isotherm studies on Nd(III) adsorption onto xanthated chitosan

Kinetics and isotherm studies on Nd(III) adsorption onto xanthated chitosan

Xanthated chitosan (XC) beads synthesized from the reaction between sulphur and hydroxyl groups were applied to adsorb rare earth metal ion, Nd(III). Adsorption of Nd(III) was found to be a function of pH of initial solution, adsorbent dosage and contact time. The optimum conditions for Nd(III) adso...

Xanthated chitosan (XC) beads synthesized from the reaction between sulphur and hydroxyl groups were applied to adsorb rare earth metal ion, Nd(III). Adsorption of Nd(III) was found to be a function of pH of initial solution, adsorbent dosage and contact time. The optimum conditions for Nd(III) adsorption were at pH 3 and adsorbent dosage of 0.02 g. Rapid adsorption process was observed as it took only 10 min for reaching the equilibrium state. Chemisorption was identified as the rate limiting step and the kinetics data correlated well with the pseudo-secondorder model. © 2016 Trans Tech Publications, Switzerland.
