| dc.description.abstract | The methyl iso-butyl ketone / water / 8-hydroxyquinoline solvent extraction system coupled with atomic absorption spectroscopy was studied with regard to its applicability to the determination of some thirteen metals. The system was found to give satisfactory results for Cd, Co, Cu, Fe, Pb, Mn, Ni and Zn. The system was found to give poor results with Cr, Mg, Ca and Sr. Analysis of the organic extract was found to enhance the sensitivity with respect to that in aqueous solution by the following multiples: Cd -- 1.8; Co -- 3.9; Cu -- 2.2; Fe -- 2.7; Pb -- 2.2; Mn -- 4.6; Ni -- 3.8; and Zn -- 1.8 times. Extraction of the various metals was found to be complete or nearly complete for the pH ranges: Cd -- 8.2 to 8.8; Co -- 6.0 to 8.0; Cu -- 3.1 to 14.0; Fe -- 2.2 to 4.8; Pb -- 7.4 to 14.0; Mn -- 8.6 to 11.6; Ni -- 4.6 to 7.5; and Zn -- 5.8 to 8.7. The system was found to be well adapted to the separation, concentration, and determination of small traces of metals from complex aqueous solution at controlled pH. | en |
