摘要：In this work, we study the extraction efficiency of Lead (II) and Cadmium (II) from an aqueous solution using some N-substituted pyridazines compounds synthesized by the solid-liquid Phase Transfer Catalysis conditions without any solvent using a Maxidigest MX 350 Prolabo microwave monomode reactor fitted with a rotational system. The extraction of heavy metals ions was carried out by liquid-liquid extraction from an aqueous solution (7.10 -5 M) by an organic solution of pyridazinic compounds in dichloromethane (7.10 -5 M). The percentage of extraction was measured by atomic absorption spectrometry using air-acetylene flame atomization. Our results show a significant affinity to Pb (II) against Cd (II).
