2-Hydroxy-5-Chlorobenzophenone Oxime [HCBO] as a gravimetric and spectrophotometric reagent for the determination of Ni(ii)

S. D. Naik, Nilesh G. Limbachiya

Abstract :

The ligand 2-Hydroxy-5-chlorobenzophenone oxime (HCBO) was developed as a new analytical reagent for the gravimetric and spectrophotometric analysis of Ni(II) ion. In the pH range of 6.0 to 10.0 this reagent gives light green precipitates with Ni(II). Job‘s method of continuous variation and Yoe and Jone‘s mole ratio method revealed the stoichiometry of the complex to be 1:2 [M:L]. The obeyence of Beer‘s law was studied and the molar absorptivity and Sandell‘s sensitivity were calculated. The reagent and its complex have been characterized by elemental analysis and IR spectra. The reagent has been used for the determination of Copper and Nickel content in German Silver.
