Spectrophotometric Determination Of Chromium (iii) And Chromium(vi) Using 2-[e)-[3-[(2-hydroxybenzylidene) Amino]phenylimino)methyl]phenol

ABSTRACT The Schiff base ligand, 2-[(E)-[{3--[(2-hydroxybenzylidene)amino]phenyl}imino)methyl]phenol was synthesized by condensing 1,3-diaminobenzene and 2-hydroxybenzaldehyde in absolute ethanol. Its Cr(III) and Cr(VI) complexes were equally synthesized. The ligand was characterized via UV, IR and NMR spectroscopy, whereas the complexes were characterized based on UV and IR spectroscopy and conductivity values. Stoichiometric studies indicated 1:1 metal to ligand ratio for both complexes. Cr(III) complex absorbed at 1042.56 cm-1 υ(C-O), 532.37 cm-1 υ(Cr-N) and 607.60 cm-1 υ(Cr-O) while the C…
