The removal of Pb(II) fromwater by biosorption processes onto malt bagasse was investigated and the kinetic and thermodynamic\nparameters were obtained; additionally a diffusion modeling was proposed. The characterization of malt bagasse was performed\nby FTIR and SEM/EDS. The experiments were conducted in batch system and an experimental design based response surface\nmethodology was applied for agitation speed and pH optimization. The kinetics of biosorption followed pseudo-second-order\nmodel and the temperature of the process affected the biosorption capacity. Isotherm models of Langmuir, Freundlich, and Elovich\nwere applied and the Langmuir model showed better fit and the estimated biosorption capacity was 29.1mg gâË?â??1.The negative values\nobtained for Ã?â?
