Asbestos fiber crystals were efficiently degraded by hydrofluoric acid, but not hydrochloric acid, sulfuric acid and nitric acid. Asbestos fiber crystals were completely degraded by 15% hydrofluoric acid within 2 hours at room temperature. The results of TEM micrographs, corresponding selected area diffraction patterns (SADP) and X-ray diffraction measurements obviously demonstrated that asbestos fiber crystals were reacted with hydrofluoric acid to generate magnesium fluoride and magnesium hexafluorosilicate. A high concentration of hydrofluoric acid remained in a wastewater after treatment of asbestos with 15% hydrofluoric acid for 2 hours was properly processed. After having processed the wastewater, the concentration of fluorine ion was 1.8 mg/<I>l</I>. These results suggest that the method consisting of a degradation of asbestos with hydrofluoric acid and a subsequent processing of wastewater may be useful for removing resolution of asbestos.
