چکیده
|
The treatment of a tannery effluent especially the elimination of chromium was made by adsorption using a mixed oxide of magnesium and aluminum obtained after calcination of a layered double hydroxide (ldh). the removal of chromium effluent is a rapid process. indeed,at room temperature (25°c),the adsorption equilibrium is reached after 30 min and its kinetics follows a pseudo- second order model. the adsorption isotherm is in good agreement with the freundlich model.
