Comparison of the Adsorption Characteristics of Expanded Bed Adsorbent with Conventional Chromatographic Adsorbent
Hu HB, Yao SJ, Zhu ZQ, Hur BK
The static and kinetic adsorption characteristics of Streamline DEAE and DEAE-Sepharose FF were studied under various operating conditions. The adsorption isotherms for the two types of adsorbents were obtained and found to fit well to a Langmuir-type expression. The adsorption kinetics of Streamline DEAE at different concentrations, temperatures, and viscosities were studied and a mathematical model including particle size distribution was developed to describe the adsorption performance of Streamline DEAE. Comparing the uptake curves of Streamline DEAE with DEAE-Sepharose FF, it could be concluded that Streamline DEAE achieves equilibrium faster to get equilibrium than DEAE-Sepharose FF, indicating that Streamline DEAE could be used in higher flow rate systems.
