ADSORBENT OF DOLOMITE-BASED HEAVY METAL OR THE LIKE, MANUFACTURING METHOD THEREFOR AND QUALITY CONTROL METHOD THEREFOR, AND ABSORPTION METHOD OF HEAVY METAL OR THE LIKE

摘要

A dolomite-based adsorbent for heavy metal, halogen and metalloid is half-fired dolomite, and a content of a residual CaMg(CO3)2 phase in the half-fired dolomite, which is analyzed using a Rietveld method by means of powder X-ray diffraction, is 0.4≤x≤35.4 (wt %), and preferably, the dolomite-based absorbent for heavy metal, halogen and metalloid further comprises ferrous sulfate.
