Abstract: Extraction experiments for Zn(II) ions from aqueous phase by new laboratory prepared Azo derivation as complex agent 2- [4-bromo-2,6-diethyl phenylazo] -4,5-diphenylimidazole(BDPI)shows the optimum conditions for this extraction method was (pH= 8) (10 minutes) shaking time and 50μg concentration of Zn(II)ions in aqueous phase. Organic solvents effect study shows there is not any linear relation between distribution ratio (D) for extraction of Zn+2 ions and dielectric constant (ε)for organic solvents used but there is in effect for organic solvent structure on the extraction of Zn+2 ions and distribution ratio (D) values. Stoichiometric studies demonstrated the more probable structure ion pair complex extracted for Zn+2 was 1:1.
