Extraction of the Perrhenate Anion Using Goethite Surface-Modified with Hydrophobic Quaternary Amines

Abstract

Goethite [FeO(OH)], the surface of which we modified by thin coatings of hydrophobic quaternary amines, has been used to extract the perrhenate anion (ReO4)- from alkaline aqueous solutions (pH 11.3). The quaternary amines were bound to the surface of the goethite by ionic association between the negatively charged inorganic surface and the positive quaternary ammonium group. However, further free amine groups were retained by hydrophobic interaction with the adsorbed layer leaving other quaternary ammonium groups free on the surface. These were capable of selectively extracting polarisable anions such as perrhenate from non- polarisable anions such as nitrate or hydroxide. The kinetics of extraction were fast (tj less than five minutes) and the capacity for perrhenate varied between 10 and 60 m mol/kg for the different modified-goethites.
