摘要

<正>The effects of pH

initial concentration and temperature on the adsorption of phenol by chitosan were investigated in this paper. The isothermal data was applied to Langmuir linear and the Freundlich linear isotherm equation

and the thermodynamic parameters （△H

△G

△S） were calculated according to the values of binding Langmuir constant

KL. Results indicated that the adsorption between chitosan and phenol was significantly physical in nature

the negative△H constant at lower temperature confirmed that more phenol was adsorbed by chitosan at lower temperature. The kinetics of the sorption process of phenol on chitosan was investigated using the pseudo-first order and pseudo-second order kinetics

and results showed that the second order equation model provided the best correlation with the experimental results.
