Abstract:
The metal complex formation between a synthetic Schiff base 4-chloro-2-
(quinolin-8-yliminomethyl)-phenol (or HClQP) and various cations of K(I), Mg(II), Al(III),
Cr(III), Mn(II), Fe(II), Co(II), Zn(II), Ce(II), and Pb(II) in ethanol was investigated by a
micro-scale UV-Visible spectrophotometric method. These absorption spectra were evaluated
with respect to Schiff base concentration and various pH of the color formation reactions. It
was found that the complexation reaction of Zn(II) and HClQP in ethanol resulted in spectral
changes in the wavelength range of 370-500 nm at pH 5.0. A distinct maximum was observed
at wavelength of 440 nm. Optimization of parameters of the Zn(II) complex formation was
carried out. This study included investigation of the time effect on the absorbance of HClQP
reagent solution (stability in time) and on the color of the product solution of Zn(II) and
HClQP reaction (completion time), the ratio of Zn(II) to HClQP ligand, the effect of reagent
concentration, and the calibration range. Under the optimum conditions, the proposed method
was successfully applied for the determination of Zn(II) in synthetic water samples.
