ABSTRACT

Extraction experiments for Zn+2 ion from aqueous phase by new laboratory prepared Azo derivation as complexation agent 2- [(4- Benzyloxy phenyl)azo]- 5- nitro-4-phenyl imidazole (BANI) shows the optimum conditions for this extraction method was (pH= 9) (10 minutes) shaking time and 100μg (1.5x10-4M) concentration of Zn+2 ion in aqueous phase. Organic solvents effect study shows there is not any linear relation between distribution ratio (D) for extraction of Zn+2 ion and dielectric constant (ε)for organic solvents used but there is un effect for organic solvent structure on the extraction of Zn+2 ion and distribution ratio (D) values. Stoichiometric studies demonstrated the more probable structure ion pair complex extracted for Zn+2 was 1:1.

Keywords: Zn (??), Solvent extraction, azo ligand.
