摘要：Experiments were carried out to study the adsorption of erythromycin(EM) in aqueous solutions on macroporous resins. The adsorption equilibrium characteristics of three types of macroporous resins, XAD7HP,XAD16 and HZ816 were evaluated. The adsorption data were correlated with the Freundlich isotherm equation. The correlation results were in good agreement with experimental data. Thermodynamic calculation and analysis showed that the process of adsorption of EM was an endothermic physical process. The entropy of the system increased in the course of adsorption.
