Adsorption of Basic Dye in Aqueous Solution by Mesoporous Carbon Materials

Abstract

Mesoporous carbon CMK-3 with high surface area and opened pore structure was used to adsorb the basic dye, Malachite green (MG). The equilibrium adsorption data was well described by the Langmuir model, and a very high Langmuir adsorption capacity was obtained by this adsorbent. The adsorption kinetics was found to be best represented by a pseudo-second-order kinetic model.
