Solvent Extraction Method for the Separation of Cerium(III) as Cations From Aqueous Media By use 4-[N-(5-methyl isoxazol-3- yl)benzene sulfonamide azo]-1- Naphthol Coupled With Spectroscopic Method For Determination
Abstract
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 .
Key word: Cerium(ΙΙ) , Solvent extraction , 4- [N-(5-methyl isoxazol-3-yl)benezen sulfonamide azo]-1- Naphthol.
