摘　　要：A study was made on the adsorption kinetics and thermodynamics of methylene blue（MB） and acid blue 80（AB80） onto powder of activated carbon（PAC） prepared by chemical method from dry potato residue（DPR）. The PAC was characterized by N2 adsorption-desorption isotherms analysis and Scanning electron microscopy. The ma- ximum adsorption capacities of PAC for MB and AB80 at 303 K are 532.19 and 156.22 mg/g, respectively. The re- suits indicate that the adsorption kinetics of the selected dyes on PAC is well-described by the pseudo-second order model. And their thermodynamic data were analyzed via the isotherms of Langmuir, Freundlich, Redlich-Peterson, Toth and Sips, and the thermodynamic parameters were calculated. The results show that PAC is a fast and effective adsorbent for removing the cationic dyes from aqueous solutions.A study was made on the adsorption kinetics and thermodynamics of methylene blue（MB） and acid blue 80（AB80） onto powder of activated carbon（PAC） prepared by chemical method from dry potato residue（DPR）.
