Spectrometric studies on the complexation of Zr(IV) with azopyrazolonic derivatives
- Mansoura Univ., Egypt
Spectrometric studies on the complexation of zirconium IV (Zr(IV)) with five new pyrazolonic derivatives were carried out. The influence of ortho-substituted groups on the operational parameters of the spectrometric method of determining Zr(IV) was investigated. The absorption spectra revealed that the wavelengths of the absorption maxima of the azopyrazolonic derivatives are different from those of the zirconium compounds. Beer-Lambert law is followed for zirconium concentrations of the order of 2.2 x 10/sup -6/ M (0.2..mu..g Zr/mL). Interferences of copper II (Cu(II)), beryllium II (Be(II)), Zinc II (Zn(II)), aluminium III (Al(III)), thallium IV (Th(IV)), uranium II (U(VI)), manganese II (Mn(II)) iron (III) (Fe(III)), cobalt II (Co(II)) and nickel II (Ni(II)) ions were investigated in connection with some masking agents such as sulfate ((SO/sub 4//sup 2 -/) and C/sub 2/O/sub 4//sup 2 -/. 5 figures, 4 tables.
