dc.description.abstract |
This investigation is concerned with the applicability of an organic reagent for the determination of nickle in aqueous solutions. A four-step synthesis was utilized for the preparation of the organic reagent, 4, 4'- dihydroxy-benzildioxime (DHBD). Para-anisaldehyde was used to prepare anisoin. Anisil, obtained from the anisoin, was used to synthesize 4,4'-dihydroxybenzil which was the precursor to DHBD. Ethanol was selected as the solvent for DHBD and a DHBD-nickel complex was studied.
The optimum wavelength for the complex was 420 nm with the absorbance measurements being made after a twenty minute color development. The effect of water in ethanol was studied as well as the effect of pH in the diluent solution. The DHBD-nickel complex conforms to Beer's Law and the metal to ligand ratio was determined to be 1:1, although a 1:2 ratio was expected. The effect of foreign ions on the absorbance of the DHBD-nickel complex was studied. |
