“…These residues seem to be a useful alternative for metal biosorption as reported in some papers where different types with different origins of sawdust were tested (Boussahel et al 2009;Bulut and Tez 2007;Elbariji et al 2006;Gad et al 2013;Hidalgo-VÁ zquez et al 2011;Samarghandi et al 2011;Vaishya and Prasad 1991). In this context, local and available pine, beech and fir sawdust's were tested and compared for their ability to lead biosorption.…”

The present paper exposes the lead adsorption from synthetic effluents using natural and available materials. Pine, beech and fir sawdust's were used and compared for their lead adsorption ability. To optimize the sorption phenomenon, some process parameters were studied namely temperature, pH, contact time, initial Pb(II) concentration, sawdust's dosage and granulometry, stirring speed and medium salinity. The materials were characterized by FTIR spectroscopy, X-ray diffraction and fluorescence. The results demonstrated that the pine sawdust gave the best level for lead adsorption (15.5 mg/g) in the following conditions and at 23 ± 2°C of temperature : pH 5.45 ± 0.05, 100 mg/L of initial Pb(II) concentration and 10 g (per liter of solution) of pine sawdust composed from granules with mean diameter lower than 500 lm. As well, the adsorption kinetics seem to satisfy to Langmuir isotherm model.
