Results on the adsorption of MnO4- ions in fixed-bed dynamics obtained on AC-400 and AC-600 adsorbents beds indicated that the AC-400 bed appears to be the most efficient in removing MnO4- ions in acidic media. Indeed, the adsorbed amounts, the adsorbed capacities at saturation and the elimination percentage of MnO4- ions obtained with AC-400 (31.24 mg; 52.06 mg·g^-1 and 41.65% respectively) were higher compared to those obtained with AC-600 (9.87 mg; 16.45 mg·g^-1 and 17.79% respectively).
