Abstract

In order to develop a treatment agent that insolubilizes fluorine in biomass ash, various phosphates compounds like calcium phosphate and aluminum phosphate or incinerated ash of sewage sludge which is containing a large amount of phosphorus components, were added to the biomass ash. The fluorine elution properties were investigated, and the solubility was significantly lowered by adding sulfuric acid or phosphoric acid to the agent, and showed effectiveness as a fluorine elution inhibitor.
