Abstract
Scorodite is an important arsenic carrier for the immobilization of arsenic generated in the metallurgical industries. The transformation of the amorphous ferric arsenate into scorodite was investigated in a mixed sulfate media (pH 1-2) and elevated temperature (80-95 °C). This transformation process has been traced via scanning electron microscopy (SEM) and X-ray diffraction (XRD). Thus, it was found that lower pH and higher temperature was favored to generate more stable scorodite. The scorodite with TCLP leachability of 3.58 mg/L As was produced at 95 °C and initial pH 1.2 for 12 h.
