ABSTRACT
Activated carbon from semi-coke (named SAC) was successfully prepared by high temperature
vapor activation. As an adsorbent, its adsorption behaviors for dyes from aqueous solutions was studied.
The porous texture parameters determined by N2 adsorption at 77 K indicated that SAC was essentially
mesoporous and had a surface area of 724.9 m2 g-1. SEM result showed clearly that the surface of
SAC was very porous. The adsorption experiment data exhibited that the adsorption capacity of SAC
increased with the contact time until adsorption equilibrium. The adsorption mechanism of SAC was
explored by isotherm and kinetic studies. It was found that the adsorption of dye followed the Freundlich
isotherm and the pseudo first-order equation.
