| Research Abstract |
Removal of harmful components from inorganic wastes by the chlorination volatilization method using the soil and the mixed salts was developed. CaCl2 was desirable as a chlorination agent because it was able to keep reacting effectively for a long time. The addition of the soil was not necessary when the waste contained high concentration of SiO2. The chlorination treatment was required about 800 to 1000℃, and it depended on the stability of lead in the waste. It is necessary to flow the carrier gas including moderate moisture.
