The first objective of the present work had been to im-prove the Fe(II)-adsorption capacity performances of the brick made by craftsmen in Central African Republic. The adsorption capacity of a new absorbent (FeOOH deposited onto 6 M HCl-treated brick pellets) was inves- tigated by carrying out column experiments, and data were compared to those obtained with untreated brick grains and ones that were previously gently treated in a 1 M HCl solution at RT before their FeOOH coating.
