2'-Hydroxy-4'-methoxychalcone Oxime [HMCO] as a gravimetric and spectrophotometric reagent for the determination of Ni(II)

Abstract :

The ligand 2‘–Hydroxy–4‘–methoxychalcone oxime (HMCO) was developed as a gravimetric and spectrophotometric reagent for the determination of Ni(II). In the pH range of 7.0 to 10.0 this reagent gives light green complex with Ni(II). Job‘s method of continuous variation and Yoe and Jones mole ratio method revealed the stoichiometry of the complex to be 1:2 [M:L]. The obeyance 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 Nickel content in German silver alloy.
