摘要：

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.
