Solubility and Fourier-Transform Infrared Spectra of Ascorbic and Pyruvic Acids with Some Metals

Abstract

In this work, the preparation of complexes containing metallic elements such as Mn(II), Fe(II), Co(II), Cu(II) and Zn(II) with ascorbic acid and pyruvic acid as ligands is presented. The characteristics of these complexes were determined and analyzed by Fourier-transform infrared (FTIR) spectroscopy, UV-visible spectrophotometry, and solubility test in polar and non-polar solvents, in addition to the determination of melting points and conductivity.
