MECHANISM OF EXTRACTION AND STRIPPING OF Fe(Ⅲ) WITH PRIMARY AMINE N1923 AS EXTRACTANT AND n-OCTANE AS DILUENT

Abstract

Abstract: Mechanism of extraction of Fe (III) from sulphate solution by primary amine N1923 and stripping of Fe loaded organic phase with dilute H_2SO_4 was investigated. The organic phase was characterized by FT-IR and photon correlation spectroscopy. The composition of extracted species as well as the content of H_2O in organic phase were determined. The dependence of both the rate of extraction and stripping on the formation of reverse micelle in primary amine (N1923)system has been confirmed. It is shown that the extraction of Fe(III) by primary amine sulphate may be related to the adduct formation or cation exchange reaction under different concentrations of H_2SO_4 in aqueous solution.

Key words: Fe(III), primary amine (N1923), extraction, stripping
