Spectrophotometric Study of U(VI) with 2-Hydroxy-4-Chloro-5-Methylpropiophenone Oxime

Abstract

In view of the growing importance of o-hydroxy ketoxime as analytical reagent, we have applied 2-hydroxy-4-chloro-5-methylpropiophenone oxime (HCMPOX) for determination of U(VI) spectrophotometrically. Stiochiometry of the complex was studied by continuous variation, the mole ratio and the slope ratio
methods which comes out to be 1 : 2 (metal : ligand). Absence
isobestic point shows that single complex species exists. The
stability constant of the complex is found to be 1.64 x 10⁶. The
structure of the complex was also studied by infrared spectra and
magnetic susceptible data.
