Activated carbons calcined at 400？C and 600？C (AC-400 and AC-600),
prepared using palm nuts, collected in the town of Franceville in Gabon, were
usedto study the dynamic adsorption of MnO4-ions in
acidic media on fixed bed column and on the
kinetic modeling of experimental data of breakthrough curves of？ MnO4-ions
obtained. 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). The breakthrough curves kinetic
