Adsorption Kinetics of Grape Seed Procyanidins on Macroporous Adsorbent Resin

Article Preview

Abstract:

Experiments were carried out to study the adsorption kinetics of grape seed procyanidins onto macroporous resin HZ818 from aqueous solutions.The effects of temperature,initial concentration and agitation on the adsorption kinetics have been investigated.Both the Lagergren-first-order equation and intra-particular diffusion model were used to describe the adsorption mechanisms. And the adsorption process were affected both by film diffusion and by intra-particle diffusion.The intra-particle diffusion rate constants increase with an increase in temperature,initial concentration and agitation speed.
