👉 An iron fluid, also known as an aqueous iron solution, is a colloidal suspension of iron ions (primarily Fe³⁺) in water. These iron ions remain dissolved due to the high dielectric constant of water, which stabilizes the ions and prevents them from aggregating. The fluid exhibits unique properties like high electrical conductivity and a reddish-brown color due to the presence of ferric ions. Iron fluids are crucial in various industrial processes, including water treatment, where they help remove impurities and heavy metals by adsorbing or precipitating them. They also play a role in environmental remediation, particularly in the treatment of contaminated groundwater and soil, by facilitating the removal of toxic iron compounds.
