Mathematical Model of Curcumin Adsorption Purification

Abstract

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 curvesand the theoretical results fit the experimental results well．

Key words: curcumin, adsorption, mathematical model
