Abstract EN
The removal of Pb(II) from water by biosorption processes onto malt bagasse was investigated and the kinetic and thermodynamic parameters were obtained; additionally a diffusion modeling was proposed.
The characterization of malt bagasse was performed by FTIR and SEM/EDS.
The experiments were conducted in batch system and an experimental design based response surface methodology was applied for agitation speed and pH optimization.
The kinetics of biosorption followed pseudo-second-order model and the temperature of the process affected the biosorption capacity.
Isotherm models of Langmuir, Freundlich, and Elovich were applied and the Langmuir model showed better fit and the estimated biosorption capacity was 29.1 mg g−1.
The negative values obtained for ΔG° and positive values of ΔH° confirm, respectively, the spontaneous and endothermic nature of the process.
The diffusion modeling was performed based on experiments in the absence of agitation to investigate the influence of the biosorbent on the sorption process of Pb(II) ions.
