In this paper, laboratory prepared azo derivative 2-[(4-Formyl phenyl) azo]-4,5-diphenyl imidazole (FPAPI) has been used as complexing agents for extraction Pb(II) and Cd(II) ions from aqueous solutions. Spectroscopy study was at λmax=533nm for ion pair complex of Pb(II) and λmax=543nm for ion pair complex of Cd(II) and all effective parameters on the extraction process were also studied. The optimum pH results for giving higher extraction efficiency of Pb(II) and Cd(II) were 8 and 9 respectively. In addition to other parameters such as shaking time, thermodynamics, an organic solvent, interferences, electrolytes, the paper has adopted different methods to determine the most feasible structural geometry of extracted ion-pair complex of [1:1]2+, anion, [Pb-FPAPI]2+, 2NO3-, [Cd-FPAPI]2+, 2NO3-.
