摘要: 研究了 D4020吸附剂吸附姜黄色素的吸附等温线和吸附柱流出曲线‚并用数学 模型对其进行了摸拟.D4020吸附姜黄色素的等温线可用 Freundlich 方程拟合‚在25℃ 时‚通过线性回归得方程系数 kf=0.3152‚指数 nf=0.7443.用常微分法对流出曲线模 型求数值解‚得到的理论流出曲线与实验结果吻合良好.

Abstract: The adsorption isotherm and effluent curves of curcumin solution on a column packed with D4020adsorbent were studied and simulated by a mathematical model.It is shown that the adsorption isotherm curves can be fitted by Freundlich equation.The coefficient kf of the equation is0.3152and the exponent nf is0.7443at25℃ by linear regression.The mathematical model was solved numerically by ordinary differential method to describe the effluent curves‚and the theoretical results fit the experimental results well.

Key words: curcumin, adsorption, mathematical model
