摘要：

An adsorbent has been prepared from Heishan coal by chemical activation with KOH, the activated carbon has a BET surface area of 801.53 m(2)/g, the meso-pore ratio is 89.63%, SEM image shows that it is very rich in pore structure. The activated carbon was used to adsorb malachite green from an aqueous solution in room temperature. The effects of pH, contact time and dosage have been studied. The results show that the adsorption of malachite green from aqueous solution onto Heishan coal-based activated carbon proceeds according to the pseudo-second-order model, the adsorption equilibrium data were better represented by the Langmuir isotherm than Freundlich isotherm.
