U.V. Spectroscopic Studies of the Schiff Base N-(o-N-(Methyl-3-ol-2-butenimino)- -(o-Toluyl)-1,2- diphenylethandimine and its Complexes with Co(II), Ni(II), Cu(II) and Pd(II): Direct Determination in Absolute Ethanol

The U.V. Spectra were used for the direct quantification of the Schiff base N-(o-N-(methyl-3-ol-2-butenimino)- -(o-Toluyl)-1,2-diphenyl-ethandimine and its complexes with Co(II), Ni(II), Pd(II) and Cu(II) in absolute ethanol at = 344 nm for the Schiff base, Co(II), Ni(II) and Pd(II) complexes and at = 260 nm for the Cu(II) complex. The direct determination limit was estimated through the plot of the molar concentration against the absorbance and R2 and R.S.D for each complex were calculated. The method appears to be in a good accuracy and precision.
