摘要
研究了ｐＨ＝３．０时紫苏色素在ＡＢ－８型大孔吸附树脂的吸附等温线和固定床吸附漏出曲线。实验结果表明，紫苏色素在大孔吸附树脂上的吸附为多分子层吸附。在固定床吸附过程中，紫苏色素在大孔吸附树脂的吸附量随色素液浓度的增加而增大。计算了不同浓度时吸附量随吸附体积的变化规律，计算结果与实验实测结果基本吻合。
The adsorption isotherm and flowing adsorption curves of Perilla pigment on AB8 macroporous adsorb resin at pH=3.0 were studied. The adsorption type of Perilla pigment on this adsorbent was polymolecular adsorption, and the adsorbing ability of the adsorbent for the Perilla pigment were influenced by the concentration of pigment in the solutions.
