The Solvent Extraction of Uranium(VI) by N-m-Tolyl-o-methoxybenzohydroxamic Acid

Abstract

A simple and rapid spectrophotometric determination of uranium(VI) is described. The uranium(VI) N-m-tolyl-o-methoxybenzohydroxamic acid complex is extracted with chloroform at pH 5.3 to 5.5 from aqueous solution. Maximum absorption of orange-red extract occurs at 510 nm. The colored complex obeys Beer's law over the range 0.3 to 20 ppm of uranium. The effect of acidity, reagent concentration, and diverse ions on the visible absorption of extracted complex has been studied.
