Comparison of the adsorption characteristics of expanded red adsorbent with conventional chromatographic adsorbent

The static and kinetic adsorption characteristics of Streamline DEAE and DE AE-Sepharose FF were studied under various operating conditions. The adsorp tion isotherms for the two types of adsorbents were obtained and found to f it well to a Langmuir-type expression. The adsorption kinetics of Streamlin e DEAE at different concentrations, temperatures, and viscosities were stud ied and a mathematical model including particle size distribution was devel oped to describe the adsorption performance of Streamline DEAE. Comparing t he uptake curves of Streamline DEAE with DEAE-Sepharose FF it could be conc luded that Streamline DEAE achieves equilibrium faster to get equilibrium t han DEAE-Sepharose FF indicating that Streamline DEAE could be used in high er flow rate systems.
