AB-8大孔树脂对葡萄籽原花青素的吸附过程
Adsorption process of proanthocyanidins in AB-8 macroporous resin
摘要
Abstract
Adsorption process of extracted proanthocyanidins from grape seed into AB-8 macroporous resin was studied. Phase equilibrium equation and adsorption dynamic model for the process were established. Overall mass transfer coefficient, mass transfer zone length and penetration time were calculated at different flow rates and feed concentrations. The results of static adsorption show that the proanthocyanidins adsorption isotherm accords with Langmuir isotherm equation. The dynamic adsorption process of proanthocyanidins to AB-8 macroporous resin is controlled by film diffusion. The calculated penetration time agrees with the experimental results. The theoretical model could be used to supervise adsorption experiment and design.关键词
