Biosorption of Ni (II) from aqueous solutions and real industrial wastewater using modified A. barbadensis Miller leaves residue powder in a lab scale continuous fixed bed column

In the present studies, adsorption behavior of modified A. barbadensis Miller leaves (MABL) residue powder, an agricultural and herbal waste was investigated to remove Ni (II) ions from aqueous solutions in a fixed-bed adsorber continuous column. Experiments at various operating conditions of bed he...
