摘要
The present invention is to provide a process for producing a scorodite that can shorten the time required for synthesizing the scorodite, and further can improve the yield of arsenic and iron into the scorodite. Accordingly, a process for producing a crystalline scorodite from an acidic aqueous solution containing pentavalent As and trivalent Fe, wherein the synthesis of the crystalline scorodite is performed after the molar ratio of trivalent Fe to pentavalent As contained in the acidic aqueous solution is adjusted to be equal to or more than 0.9 and equal to or less than 1.1 is provided.
