Removal of arsenic from aqueous solution in the form of scorodite is one of the promising processes for the disposal of arsenic-containing wastewater. While it suffers from the strict reaction conditions including high Fe/As molar ratio, narrow pH range, and low Fe/As supersaturation when the liquid iron sources of Fe²⁺/Fe³⁺ are used as the iron sources.
