Short communication : UV-spectroscopic characterization of the schiffs base N,N bis-salicildene-o-phenylenediimine and its complexes with some metal ions

الملخص EN

The synthesis and characterization of N, N bis-salicildene -o- phenylenediimine was described, using infra red, ultra violet spectroscopy, melting point, and elemental analysis for nitrogen.

The behavior towards some metal ions Fe (II), V (V), Co (II) is studied and its possibility as analytical reagent evaluated.

V (V)-NNSP absorbance increased by 17 % in the presence of 0.064 M hydrochloric acid, while Co (II)-NNSP and Fe (II)-NNSP absorbances increased by 116.27 % and 225.2 % respectively in the presence of 0.25 M and 0.15 M ammonia.

This reagent can be used quantitatively to determine trace concentr-ation of metal ions Fe (II), V (V), Co (II) in optimum conditions as described in this paper.
