Title:
六価クロムの還元方法、成形体の製造方法及び地盤改良方法
Document Type and Number:
Japanese Patent JP5602848
Kind Code:
B2
Abstract:
Disclosed is a method for reducing hexavalent chromium, which is characterized by bringing an alkalophilic microorganism belonging to the genus Cellulomonas into contact with a hydraulic material that contains hexavalent chromium, an aqueous solution of said hydraulic material being alkaline. A reducing sugar, a reducing agent and blast furnace slag may be additionally blended in the hydraulic material.
