摘要
研究了XDA-1B大孔吸附树脂柱层析法对鼠尾藻多酚吸附解析条件。结果表明:最佳静态吸附条件为:温度30℃、样品中多酚浓度2.5 mg/mL,XDA-1B大孔吸附树脂适用于鼠尾藻多酚的分离纯化。上样流速2.0 mL/min,洗脱流速2.0 mL/min条件下,XDA-1B大孔吸附树脂对鼠尾藻多酚的吸附和脱附速率较快,2 h之后趋向吸附饱和脱附完全。Freundlich吸附经验公式适于其吸附曲线模拟。
In this paper,the analytical conditions for the adsorption of polyphenols on the seaweed by XDA-1B macroporous resin were studied. The results showed that the optimal conditions for static adsorption were as follows： temperature 30 ℃,polyphenol concentration in the sample 2.5 mg/mL,and XDA-1B macroporous adsorption resin was suitable for the separation and purification of polyphenols from Sargassum thunbergii.With the sample flow rate of 2.0 mL/min and the elution flow rate of 2.0 mL/min,the adsorption and desorption rate of the polyphenols on the XDA-1B macroporous resin was faster and the adsorption equilibrium was reached after 2 h,and Freundlich adsorption empirical formula is suitable for the adsorption curve simulation.
