【摘要】 本文研究了葡萄籽提取液中的原花青素在X-5大孔吸附树脂上的吸附行为。在实验条件下,达到吸附平衡的时间为60min;实验测定的吸附等温线符合Freundlich 方程;根据穿透曲线测定了动态吸附容量为164.6mg/g树脂,总传质系数KFav为0.018s-1,传质区长度为15.9cm。更多还原

【Abstract】 In this paper, adsorption behavior of proanthocyanidin extracted from grape seed on X-5 macro porous adsorptionresin was studied. In experiment conditions the adsorption equilibrium time was 60min; The results of experiment indicated thatadsorption isotherm was correlated with a Freundlich-type of isotherm equation. The dynamic adsorption capacity measuredfrom breakthrough curve was 164.6mg/g resin, the total transfer mass coefficient 0.018s-1, and the height of mass transfer zone15.9cm.更多还原
