| 摘 要： | A study on adsorption of Acidic Blue RAWL and Cationic Blue X-GRRL dyes by chitosan have been conducted. The adsorption kinetic parameters including adsorption rate K and effective diffusing coefficient D'i under the optimal pH ranges have been determined. Analysis through the enthalpy calculation reveals a substantial thermodynamic difference between the adsorption processes of the two dyes, which helps to understand the adsorption mechanism by chitosan.
