Practical Model Experiment of Asbestos Waste Chemical Decomposition using Acid
Acid treatment was investigated for the practical chemical decomposition of asbestos-containing waste. Chemical decomposition of all six of the most hazardous asbestos was confirmed using actual waste speci-mens. Chrysotile was decomposed chemically using strong acids : HCl, H 2 SO 4 , and HNO 3 . Molding materials containing calcium components more than spraying materials required large amounts of H 2 SO 4 , but the calcium component did not influence treatment with HCl. Amphiboles of five kinds were chemically decomposed with mixed acids containing hydrofluoric acid. Hydrofluoric acid used as a mixed acid was more effec-tive than single acids for these reactions.
