In the present paper, the lignocellulosic residues from the olive oil industry in South-East Italy, namely BOP (Biosorbent from Oil Production), were used as sorbents for heavy metals retention (Pb+2, Cd+2, Ni+2) in water and wastewater treatments. To the purpose, thermodynamic and kinetic investigations for single and multispecies systems were carried-out through batch equilibrium isotherms and column dynamic experiments. In the case of batch tests, maximum metals retentions (q(max)) in single ion solutions were 22.4 mg/g(Bop), 10.5 mg/g(Bop), 5.04 mg/g(Bop) respectively for Pb+2, Cd+2 and Ni+2, lower figures were detected in the case of ternary systems with values exceeding 10.51 mg/g(Bop), 5.11 mg/g(Bop), 3.81 mg/gBop respectively. Further drastic reductions were detected in tap water. Langmuir and Freundlich isotherms led to good correlations of the data in single-ion and ternary solutions in demineralized water. Freundlich isotherms gave better correlation in tap water. In the case of column tests, operating capacities resulted in the same order with Pb+2> Cd+2>Ni+2. After retention, the exhausted metal converted materials were included into cement conglome rates for a possible employment in the building industry applications, thus minimizing their potential environmental impact.
