Quaternary ammonium cations (or quats) and Na + were used as model interfering ions that could possibly influence the uptake of Pb 2+ in wastewater by dead algal biomass of Sargassum ilicifolium. This biosorption study consisted of four sets of batch experiments: Pb 2+ ; Pb 2+ /Na + ; Pb 2+ /quats; Pb 2+ /Na+/quats. The effect of the presence of ions other than Pb 2+ on the maximum extent of adsorption on the biomass was determined. Equilibrium data gathered suggested that improved Pb 2+ adsorption could occur in the presence of quats. On the other hand, the presence of Na+ lowered the maximum extent of adsorption of Pb 2+ , particularly at low initial concentrations of Pb 2+ . In the presence of both Na + and quats , more Pb 2+ were adsorbed than when only one type of interfering ions was present.
