摘要：

In this work, the synthesis of new organic compounds is reported based on pyridazin-3-(2H)-one compounds. The extraction efficiency of metal ions (e.g. Lead Pb(II), Cadmium Cd(II), Copper Cu(II) and Zinc Zn(II)) from aqueous solutions to organic solutions of those compounds was studied. Accordingly, the studied ligands show a remarkable affinity for the transition metals, especially Zn(II) with (Ligand L-5), Cu(II) and Cd(II) with (Ligand L-3) in the presence of withdrawing and donor electron group. Theoretical calculations DFT were made in order to get better insight into the geometry of the studied ligands. (C) 2019 Elsevier B.V. All rights reserved.
