摘要

The present invention relates to a method for restoring arsenic contaminated soil. According to the present invention, arsenic can be separated from soil particles by washing arsenic contaminated soil using a basic solution and irradiating ultrasonic waves. Also, the surface of silicate minerals is partially melted using the basic solution and a manganese oxide is exposed to the basic solution so residual arsenic can be removed.
