Two new macrocyclic hydrazone Schiff bases were synthesized by reaction of succindihydrazide and adipdihydrazide with acetylacetone. Hydrazones have been characterized by elemental analyses and IR, mass, 1 H NMR, and 13 C NMR spectral data. Hydrazones have been studied by liquid-liquid extraction towards the s-metal ions (Li + , Na + , and K + ) and d-metal ions (Cu 2+ and Cr 3+ ) from aqueous phase to organic phase. The effect of chloroform and dichloromethane as organic solvents over the metal chlorides extraction was investigated at 25 ± 0.1°C by using flame atomic absorption. We found differences between the two solvents in extraction selectivity.
