The aim of this study is to report batch adsorption results of Cd (II) and Cr (VI) onto Algerian bentonite. The equilibrium adsorption process was achieved at about 120 min contact time. The kinetic and isotherms aspects of Cr (VI) and Cd (II) adsorption were investigated by varying operation parameters such as pH ( 6), initial Cd (II) and Cr (VI) concentrations (50 200 mg/l) and ...
as adsorbent purification process of patchouli oil. Bentonite and Zeolite can be utilised as adsorbents because their properties and absorbency are influenced by the presence of pore spaces between the clay mineral bonds and the imbalance of electrical charges in their ions. After adsorption, there was a decrease in Fe content and
