Abstract

PURPOSE: To stabilize by solidifying hexavalent chromium and to prevent the reelution of it for a long time, by using cement added barium chloride, on occasion of solidifying the harmful hexavalent chromium by portland cement.
CONSTITUTION: Industrial waste substance etc. containing harmful hexavalent chromium, is solidified by hydraulic portland cement added 1W16% of barium chloride. Environmental polution is not caused extending over a long time, because insoluble barium chromate is formed in an alkaline domain by reacting hexavalent chromium with barium chloride and is fixed in the cement stably.
