Abstract


The ligand 2'-Hydroxy-4'-butoxychalcone oxime (HBCO) was developed as a new analytical reagent for the spectrophotometric analysis of Fe (III) ion. In the pH range of 2.0 to 4.5 this reagent forms 70% aqueous ethanol soluble purple colored complex with Fe (III). Job's method of continuous variation and Yoe and Jone's mole ratio method revealed the stoichiometry of the complex to be 1:1 [M:L]. The obeyence of Beer's law was studied and the molar absorptivity was calculated. The reagent has been used to determine iron in medicinal sample "Fefol".
