Journal Title:Journal of Chemical, Biological and physical sciences

The ligand 2'-Hydroxy-4'-butoxychalcone oxime (HBCO) was developed as a gravimetric and spectrophotometric reagent for the determination of Pd(II) ion. In the pH range of 2.0 to 5.0 this reagent forms 70% ethanol soluble yellow colored complex with Pd(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 was calculated.
