  • METHOD FOR TRANSFORMING ARSENIC SULFIDE SLAG AND CURING AND STABILIZING RESULTING COMPOUND BY MEANS OF MICROENCAPSULATION
    Publication number: 20210078056
    Abstract: The present disclosure provides a method for transforming an arsenic sulfide slag and curing and stabilizing the resulting compound by means of microencapsulation, comprising the following steps: (1) preparing arsenic trioxide from the arsenic sulfide slag as a raw material; (2) preparing 4-hydroxy-3-nitrophenylarsonic acid from the arsenic trioxide as a raw material; (3) preparing an iron-manganese dinuclear cluster metal arsenate compound having a porous structure; (4) subjecting the iron-manganese dinuclear cluster metal arsenate compound having a porous structure to surface coating with silicon; (5) synthesizing an Fe(0)/Al-SBA-15 mesoporous composite stabilizer by a hydrothermal reaction; and (6) subjecting the silicon coated iron-manganese dinuclear cluster metal arsenate compound to curing and stabilizing treatment by means of microencapsulation.
