Study on Adsorption Performance of TP in Expanded Bed

Abstract

Abstract: The adsorption performance of TP (tea polyphenols) was investigated in expanded bed with the resin H103. Theresults from the analyses of static and dynamic adsorption suggested that the adsorption effect of tea infusion in expanded bedwas better than in packed bed. The adsorption isotherms might be described by Langmuir equation and the adsorption kineticsequation expressed as At=aeb/t. Furthermore, the adsorption amount could be improved in expanded bed by adjusting theconcentration of tea extracts.

Key words: H103 resin, TP, expanded bed adsorption, adsorptive kinetics
