Extraction and Photometric Determination of Uranium(VI) by N-Phenyl-2-naphthohydroxamic Acid
Journal Article

· Separation Science
A new reagent, N-phenyl-2-naphthohydroxamic acid (N-P-2NHA), for the determination of microgram amounts of uranium (VI) is reported. Uranium is extracted from chloroform solution of N-P-2-NHA at pH 4.0 to 4.5. The orange-red extract has maximum absorption at 515 nm. The extracted complex obeys Beer's law at 515 nm and the sensitivity is 0.01 mu g U/cm/sup 2/. The color is stable for 15 days. The effects of pH, reagent concentration, and diverse ions on extraction are discussed.
