Abstract :
The ligand 2–Hydroxy–4–methoxychalcone oxime (HMCO) was developed as a gravimetric and spectrophotometric reagent for the determination of Cu(II). In the pH range of 3.0 to 6.0 this reagent gives own complex with Cu(II). Jobs 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 Beers law was studied and the molar absorptivity and Sandells sensitivity were calculated. The reagent and its complex have been characterized by elemental analysis and IR spectra. From TGA, the energy of activation was also calculated using Broido method for the first step decomposition. The reagent has been used for the determination of Copper content in Brass alloy.
