Descripción general

Ammonium iron(II)sulfate is a light green to blue crystalline powder, which dissolves readily in water, but is insoluble in ethanol and acetone. The salt melts and begins to decompose at 100 °C. It is a double salt of iron sulfate and ammonium sulfate and is made by dissolving equimolar iron(II) sulfate and ammonium sulfate in water and crystallizing the product.

Aplicación

Ammonium iron(II) sulfate hexahydrate can be used:
  • As a precursor to synthesize iron oxide nanoparticles deposited over bismuth carbonate/ACF(fiber). This material can be used as an efficient catalyst for wastewater treatment.
  • As a negative electrolyte to develop a vanadium/iron redox flow battery (V/Fe RFB).
  • To modify methyl orange dye via metal insertion reaction. The modified dye acts as a light harvester on DSSC (Dye-Sensitized Solar Cell).
  • As a dopant to prepare nano-titania catalyst by the sol-gel method. The doping with (NH4)2Fe(SO4)2·6H2O leads to photocatalytic activation of titania in the visible light range.
