U. V. derivative spectra studies of some Schiff’s bases of amino acids complexes-trace amount determination

الملخص EN

According to the biological and industrial importance of Schiff bases derived from amino acids, the U.V.

derivative spectra were studied for Schiff bases derived from Leucine amino acid and their complexes with Ni (II) and Co (II) in ethanol as solvent.

The plot of the molar concentration versus the absorbance result in a straight line relationships obeys the Beer’s Lambert law within certain ranges of concentrations.

The Zero, first and second order derivative spectra were recorded and the integrated area under the peaks estimated for a solutions of different concentrations which employed for quantification of the complexes of these Schiff bases and shows a relative enhancement in the determination limits as compared with Zero- order technique.
