Resumen

TEWARI, Brij B et al. Critical reviews on stability and Photosensitizer potential of metal ferrocyanides: a possible prebiotic mineral; part (II). Rev. Bol. Quim [online]. 2018, vol.35, n.1, pp.15-30. ISSN 0250-5460.

Aluminum, barium, chromium, indium, platinum, stannous and vanadium ferrocyanides were synthesized and characterized by elemental analysis and spectral studies. Stability of synthesized metal ferrocyanides were recorded in heat, light (UV, VIS), various concentrations of acids (HCl, H2SO4), various concentrations of bases (NaOH, KOH, NH4OH), sea water and from faucet at room and boil temperature. Stability of synthesized metal ferrocyanides was also recorded in organic solvents (ether, acetone, ethanol, formaldehyde) at room temperature. The oxidizing and photosensitizing potential of synthesized metal ferrocyanides were tested using potassium iodide and freshly prepared starch solution. The hexacyanoferrate (II) complexes of chromium, indium and platinum were found to be possible oxidizer and photosensitizer during the course of chemical evolution on primitive earth.

Palabras clave : Metal ferrocyanides; Stability; Oxidizer; Photosensitizer.
