The objective of this study is the removal of chromium from tannery wastewater by electrosorption
on carbon prepared from lignocellulosic natural residue "peach stones' thermally
treated. The followed steps for obtaining coal in chronological order were: cleaning, drying,
crushing and finally its carbonization at 900°C. The characterization of the carbon material
resulted in properties comparable to those of many coals industrially manufactured. The
study of the dynamic adsorption of chromium on the obtained material resulted in a low removal
rate (33.7%) without applied potential. The application of negative potentials of -0.7
V and -1.4 increases the adsorption of chromium up to 90% and 96% respectively. Whereas
a positive potential of +1.4V allows desorption of the contaminant of 138%.
