Extraction experiments for Ce+3 ion from aqueous phase by new laboratory prepared Azo derivation as complexation agent 4- [N-(5-methyl isoxazol-3-yl)benezen sulfonamide azo]-1- Naphthol (AMBN) shows the optimum conditions for this extraction method was (pH= 9) (10 minutes) shaking time and 100μg (1.5x10-4M) concentration of Ce+3 ion in aqueous phase.

Organic solvents effect study shows there is not any linear relation between distribution ratio (D) for extraction of Ce+3 ion and dielectric constant (ε)for organic solvents used but there is un effect for organic solvent structure on the extraction of Ce+3 ion and distribution ratio (D) values.

Stoichiometric studies demonstrated the more probable structure ion pair complex extracted for Ce+3 was 1:1 .
