Solvent Extraction and Spectrophotometeric Determination of U (VI) By Using Acetophenone 2’, 5’-Dihydroxy, Semicarbazone as an Analytical Reagent

Abstract

A spectrophotometric method has been developed for the determination of U(VI) using Acetophenone 2’,5’dihydroxy, semicarbazone1 as an extractive reagent .The reagent form a colored complex which has been quantitatively extracted into n- Butanol at pH 6.0. The method obeys Beer’s law over a range of 1 to 10 ppm. The molar absorptivity is 6785.7 L mol-1cm-1 and Sandell’s sensitivity is 0.03508 μg cm-2 respectively. The propose method is very sensitive and selective. This method has been successfully applied to synthetic and commercial samples.
