The adsorption kinetics of strong alkaline anion exchange fiber for Cr (VI) from aqueous solutions was investigated. The adsorption was a fast process. Kinetics data for adsorption of Cr (VI) from aqueous solutions were in good agreement with the pseudo-second rate equation within an initial concentration range of 50-500 mgL-1. Both the equilibrium capacity and initial adsorption rate increased with an increase in Cr (VI) initial concentration. The adsorption process had combined control by chemisorption and physisorption, including film diffusion and intra-particle diffusion.

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.
