Description
  • Abstract en Characteristics of the cadmium adsorption and desorption of a chelating resin CR11 was studied. The Langmuir adsorption model modified for the competitive adsorption of cadmium ion and hydrogen ion was applied to describe the effect of pH on the cadmium adsorption of the chelating resin. The adsorption model well described the experimental data and the maximum adsorption capacity and the adsorption constants of cadmium ion and hydrogen ion were determined. The cadmium desorption efficiency form the chelating resin by an eluent(HCI solution) could also be predicted by the adsorption model. The cadmium removal from the eluent by electrolysis was examined for the reuse of the eluent in the regeneration process of chelating resin. The experimental data well followed the pseudo-first order kinetic model and the kinetic constant was determined. The kinetic constant increased with the increase of electric current up to 0.13 A.
