The aim of this work is the study of te adsorption process of some heavy metals like lead, copper, chrome and nickel in agricultural argilaceous soil in order to put in evidence the influence of adsorption conditions on adsoption process. The adsorption isotherms, Langmuir and Freundlich, have been used to describe the adsorption equilibrium. The experimental data put in evidence that the adsoption capacity of heavy metals increases in order Ni2+ (about 110 μmol/L), Pb2+ (about 150 μmol/L), Cr3+(about 300 μmol/L) and Cu2+(about 350 μmol/L). In all cases, the Langmuir isotherms reflect more exactly the adsorption process, being recomendet for thermodynamic parameters determination.
