METHOD OF MANUFACTURING SCORODITE |
摘要 |
The present invention provides a method for manufacturing scorodite in which scorodite may be obtained. at high production efficiency and a high As concentration ratio. The present invention provides a method for manufacturing crystalline scorodite from acidic aqueous solution containing pentavalent As and trivalent Fe, the method comprising a step for adding a basic sodium compound to the acidic aqueous solution such that the sodium concentration in the acidic aqueous solution becomes larger than 0 g/ L and equal to or less than 4 g/L.
