INSOLUBILIZATION MATERIAL OF HEAVY METAL OR THE LIKE AND MANUFACTURING METHOD THEREFOR, QUALITY CONTROL METHOD OF INSOLUBILIZATION MATERIAL OF HEAVY METAL OR THE LIKE, AND INSOLUBILIZATION METHOD OF HEAVY METAL OR THE LIKE

摘要

To provide an insolubilization material of heavy metal of the like, excellent in insolubilization function of heavy metal or the like such as selenium, especially not only tetravalent selenium (hereafter "selenium (IV)", but also hexavalent selenium (hereafter "selenium (VI)" or fluorine, a manufacturing method therefor, a quality control method of the insolubilization material of heavy metal or the like, and an insolubilization method of heavy metal or the like.SOLUTION: There is provided an insolubilization material of heavy metal or the like containing burned dolomite having content of CaCOof 0≤x≤75.5 (mass%), and content of CaO of 2.3≤x≤75.5 (mass%), and a reductant with a mass ratio of 9:1 to 1:9. The burned dolomite is prepared by mixing and burning a raw material to have content of CaCOof 0≤x≤75.5 (mass%), and content of CaO of 2.3≤x≤75.5 (mass%), and the resulting burned dolomite and the reductant is blended at the mass ratio of 9:1 to 1:9.SELECTED DRAWING: Figure 1
