Abstract
Spanish title; Revisiones críticas sobre la estabilidad y el potencial fotosensibilizante de complejos metálicos de hexacianoferrato (II): un posible mineral prebiótico. Los complejos de hexacianoferrato (II) o ferrocianuros metálicos de bismuto, cadmio, cobalto, manganeso, níquel, plomo, antimonio y zirconio fueron sintetizados y caracterizados por estudios espectrales elementales. La estabilidad de los complejos metálicos de hexacianoferrato (II) fue registrada bajo condiciones de calor, luz (UV, VIS), diferentes concentraciones de varios ácidos (HCl, H2SO4, HNO3), diferentes concentraciones de varias bases (NaOH, KOH, NH4OH), y agua de mar y agua potable. La actividad fotosensibilizadora de los complejos metálicos fue probada mediante el uso de yoduro de potasio y solución de almidón. Los ferrocianuros de niquel, antimonio y zirconio fueron determinados como posibles fotosensibilizadores durante el curso de la evolución química en la era terrestre primitiva.
Bismuth, cadmium, cobalt, manganese, nickel, lead, antimony and zirconium hexacyanoferrate (II) complexes or metal ferrocyanides were synthesized and characterized by elemental and spectral studies. Stability of metal hexacyanoferrate (II) complexes were recorded in heat, light (UV, VIS), different concentrations of various acids (HCl, H2SO4, HNO3), different concentration of various bases (NaOH, KOH, NH4OH), sea and tap water.The photosensitizing activity of metal hexacyanoferrate (II) complexes were tested by using potassium iodide and starch solution. Nickel, antimony and zirconium ferrocyanides were found to be possible photosensitizer during the course of chemical evolution on primitive Earth.
