Abstract: Thermodynamics of the adsorption of Zwittermicin A by D151 cation exchange resin was studied using a static adsorption method. Adsorption equilibrium data for the adsorption of Zwittermicin A at 288 K, 298 K, 318 K and investigating concentration range were obtained and found to follow the Freundlich-type isotherm equation. The results indicated that the adsorption process of Zwittermicin A by D151 cation exchange resin was a spontaneous, exothermic and favorable adsorption.

Key words: Zwittermicin A, Cation-exchange resin, thermodynamic properties
