Rapid Solvent Extraction of Uranium(VI) with N-Phenylbenzohydroxamic Acid |
| |
Abstract: | Abstract A rapid method for the simultaneous solvent extraction and spectrophotometric determination of macro-amounts of hexavalent uranium with N-phenyl-benzohydroxamic acid is described. The intense blood-red colored complex thus extracted from chloroform at pH ~ 4 absorbs at around 510 nm. A clean-cut separation from many commonly occurring metal ions is easily accomplished. Effects of acidity, reagent concentration, and diverse ions on the visible absorption of the extracted complex have also been investigated. |
