| Abstract: | Adsorption equilibrium and kinetics were studied for the binding of Bovine Serum Albumin to Streamline DEAE and DEAE Sepharose FF.The static adsorption performance in Streamline DEAE was similar to that of in DEAE Sepharose FF,while the dynamic adsorption characteristics were different.A model for describing the dynamic adsorption was presented,and the film diffusion coefficients and pore diffusion coefficients were determined using this model and the dynamic adsorption data. |
