摘　　要：The synthesis and characterization of N,N＇-bis（salicylidene） ethylenediamine, Salen said that were carried out. The behavior of this ligand has been studied in solution in solvent homogeneous and heterogeneous systems in sulphate medium. The use of pH-metric titration, GRAN and JOB＇s methods have permitted the determination of different parameters governing the behavior of Salen in solution such as the acidity constant, the stability constant, the nature of the interaction solvent-solute, the solvation number, the stoichiometry of extracted complex etc.. Then the extraction of the Salen was finally undertaken to words the copper （II） sulfate medium. The pH of complexation, extraction time, the number of protons exchanged and the number of ligands have been finally determined.

关 键 词：Salen copper （II） metal complex acid-base behaviour liquide-liquide extraction.
