Study on dynamic adsorption and chemical regeneration of Cd(II) from textile effluents by new granular composite based on gluten

Composite granules (named Fe-PILMG) based on both an Algerian montmorillonite with iron and gluten as an inert binder are prepared and used in the elimination of cadmium by dynamic adsorption in fixed bed columns. This study is essentially focused on the adsorption of Cd (II) in dynamic mode on a fixed bed based on Fe-PILMG sorbent granules followed by a study on the chemical regeneration of these new saturated adsorbents. The various regeneration tests are carried out with NaOH solution. The experimental data on the elimination of Cd (II) (pH = 7, T = 20
