Synthesis and characterization of bisaldehyde ligand with some transition metals and its application in spectrophotometric determination of Fe(III) in natural water samples using recovery test

Abstract

The coordination behaviour of the bisaldehyde organic ligand with different coordination sites are investigated, towards some bi-and trivalent metal ions like Cr(III), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II). The solid chelates of the bisaldehyde are prepared and subjected to many analytical techniques such as elemental analyses, IR, 1 H NMR and solid reflectance spectra, magnetic moment, molar conductance, X-Ray diffraction (XRD) and thermal analyses. The chelates have octahedral geometry. The bisaldehyde ligand and its binary chelates were subjected to thermal analyses and the different activation thermodynamic parameters were calculated from their corresponding DTG curves. The biological activity of the bisaldehyde ligand and its complexes were also screened. The bisaldehyde ligand is utilized for spectrophotometric determination of spiked Fe(III) in natural water samples using recovery test under optimal experimental conditions.
