  • Can ferrous sulfate be used for environmental remediation?
  • The main application of ferrous sulfate for environmental remediation is related ot water and wastewater treatment when FeSO 4 (as a coagulant) could be used as solid waste or after pretreatment methods.
  • Why is ferrous sulfate a problem in China?
  • Ferrous sulfate from the manufacture of TiO 2 using the sulfate method leads to the generation of more than 7 million tons of ferrous sulfate waste every year in China, which leads to the storage of a large amount of waste and the increase of environmental protection costs [ 68, 86 ].
  • Why do we use ferrous sulfate based nanomaterials?
  • In order to protect natural resources, correlated with Fe behavior in natural environments, and in harmony with waste management and circular economy, the use of Fe sources from industrial ferrous waste, either in the form of ferrous sulfate or transformed into Fe-based nanomaterials, ensures environmental and economic benefits.
  • What is the crystallization process of ferric sulfate hydrate Fe2(SO4)3 xH2O?
  • In present study the crystallization process of ferric sulfate hydrate Fe2 (SO4)3.xH2O from rich in Fe (III) sulfate waste solutions was investigated. These solutions were obtained after autoclave oxidation of pyrite concentrate. They are characterized with high concentrations (> 60 g l-1) of ferric ions and sulfuric acid.
