摘要

The objective of this study is the removal of lead from aqueous solution by electrosorption on carbon prepared from lignocellulosic natural residue "date stones". The electrosorption efficiency was evaluated after the thermally treatment of the raw material at 900 degrees C. Adsorption of lead from aqueous solution by activated carbon electrodes was investigated through electrosorption experiments by changing potentials from +/- 0.05 to +/- 0.5 V/SCE. The results allow to observe that the application of a negative potential (-0,13 V) increases the adsorption capacity until 17.71 mg/g, while a positive potential (+0,13 V) released lead from the activated carbon up to 17.02 mg/g, showing the reversibility of the sorption process.
