The biosorbents were characterized through scanning electron microscopy, Brunauer-Emmett-Teller analysis, and Fourier transform infrared spectroscopy. Variables such as pH (2-12), biosorbent particle size (200-1,400μm), adsorbent dosage (0.25-1.75g/l), and agitation time (5-80min) were investigated. The suitable pH range, particle size, adsorbent dosage, and agitation time for the removal of both metals were 5 to 6, 200μm, 1g/l, and 40min, respectively. Under optimum conditions, OPB showed the highest adsorption efficiency of 80% and 78% for lead and iron, respectively. The adsorption equilibrium data were fitted to three adsorption isotherm models. The Langmuir isotherm showed the best result for both metals. The kinetics of the biosorption process was analyzed using pseudo-first-order and pseudo-second-order models. The latter showed a better fit for both metals. OPB biomass introduced the lowest chemical oxygen demand into the treated solution, with an average amount of 32.9mg/l.
