| This paper deals mainly with the adsorption and elution performances of strong basic anion exchange resins to recover cyanide. Through the experiments, D2-1 resin and 201× 7 resin were selected, respectively. By considering the initial pH value, temperature, concentration, etc. effective factors, the paper was focus on optimizing the adsorptive condition, determining the capacity of saturation adsorption and the regularity of dynamics and thermodynamics. At the same time, a neutral strip agent was selected. It avoids the production of HCN, which used to be produced in the course of elution by acid strippant, and makes the recovery process safer and more effective. The optimum conditions for cyanide adsorption were obtained: the pH value 10 to 11, normal temperature and static state for 15 minutes. The results show that the capacities of static saturation adsorption for cyanide of these two resins are 15.40mg/mLwet resin and 25.39mg/mLwet resin, respectively. The speed constants of adsorption and elution for D2-1 resin are k=1.04×10-2s-1 and k=1.48×10-2s-1 respectively, for 201×7 basic anion exchange resin are k=1.01×10-2s-1 and k=2.12× 10-2s-1 respectively. The adsorption processes of these two resins are consistent with Freundlich's equation. The results illustrate that the adsorptive performance of 201× 7 resin is better than that of D2-1 resin. Therefore 201× 7 resin has the prospect of industrial application for disposal and recovery of cyanide, In additional, the adsorptive mechanics of 201× 7 resin for cyanide were primarily discussed. It seems that hydrogen bond and physical adsorption was formed. This study will be beneficial to industrial application of resin for the recovery of cyanide.
