Perspective. Analytical validation of a general protocol for the preparation of dose-controlled solutions in aluminium toxicology

Abstract

Aluminium(III) solutions suitable for careful toxicological investigation both in vivo and in vitro, are prepared from AlCl3·6H2O and from neutral metal complexes, Al(lactate)3, Al2(citrate)2(H2O)6, Al(acetylacetonate)3 and Al(maltolate)3, by dissolving the pure compounds in TRIS-HCl buffer solutions. The metal concentrations in the supernatant liquids are determined spectrophotometrically under reproducible conditions. Al(acetylacetonate)3 and Al(maltolate)3 are detected as molecular entities by using 1H NMR spectroscopy down to concentrations of 200 and 100 µmol l–1, respectively.
