| titleOfInvention | How to prevent elution of heavy metals |
| abstract | <P>PROBLEM TO BE SOLVED: To provide a method for preventing the elution of heavy metals which can reduce the elution of lead as compared with the case when phosphoric acid alone is added to fly ash when a combustion exhaust gas is sprayed with an alkali metal compound containing carbonic acid such as sodium hydrogen carbonate. <P>SOLUTION: The combustion exhaust gas is added with the alkali metal compound containing carbonic acid by spraying. The fly ash is added with a calcium compound, the pH of an elute indicated by Environment Agency Notification No.13 test (L/S=10) is adjusted to be 8-11, and the calcium ion concentration of the elute is adjusted to be at least 50 mg/L. As the calcium compound, specifically, slaked lime, calcium chloride, unslaked lime, calcium nitrate, calcium nitrite, calcium silicon, calcium acetate, etc., and organic acid calcium salts are exemplified. Among them, slaked lime and calcium chloride are good in calcium solubility and suitable. <P>COPYRIGHT: (C)2011,JPO&INPIT |
