Patent number: 10046333Abstract: Provided is a method of restoring arsenic-contaminated soil. In the present invention, arsenic may be easily separated from soil particles by washing the arsenic-contaminated soil by using a basic solution and simultaneously irradiating the soil with ultrasonic waves. Also, since iron oxide and manganese oxide are exposed to the basic solution by dissolving a portion of the surface of a silicate mineral using the basic solution, a residual form of arsenic may be removed.Type: GrantFiled: January 12, 2016Date of Patent: August 14, 2018Assignee: KOREA INSTITUTE OF GEOSCIENCE AND MINERAL RESOURCES (KIGAM)Inventors: Jae Gon Kim, Chul Min Chon, In Hyun Nam, Jung Hwa Lee, Yong Chan Cho, Dong Hyun Seok
