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

PROBLEM TO BE SOLVED: To provide an adsorbent of a dolomite-based heavy metal or the like which is semi-burnt dolomite excellent in adsorption removal rate of heavy metal or the like without depending on production places, burning conditions or the like of a dolomite ore which is a raw material, a manufacturing method therefor and an absorption method of heavy metal or the like.SOLUTION: The adsorbent of a dolomite-based heavy metal is a semi-burnt dolomite having enhanced adsorption removal ate of heavy metal or the like, content of a retained CaMg(CO)phase in a dolomite burnt article analyzed by using a Rietveld method with powder X-ray diffraction of 0.4≤x≤35.4 (mass%), and preferably contains further ferrous sulfate.SELECTED DRAWING: Figure 1
