摘要: 本文考察了以H103树脂为介质的膨胀床对茶汤中的茶多酚的吸附性能。通过静态、动态吸附实验结果表明:膨胀床对茶汤中茶多酚的吸附比固定床对茶多酚吸附的效果好; H103对茶多酚的吸附等温线可用Langmuir公式描述;吸附动力学曲线可用At=aeb/t方程模拟;采用一定的浓度梯度,可以提高膨胀床中H103对茶多酚的吸附量。

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.
