Ferrite-Induced Immobilization of Pb-Contaminated Soil and Application of Magnetic Separation
GeoCongress 2008(2008)
Abstract
The ferritization method is applied to Pb-contaminated soil. In order to confirm the immobilization effect by ferritization, artificial Pb-contaminated soil was prepared and batch tests were performed. From the test results, it was confirmed that the insoluble effect of the ferritization-treated soil for Pb-contaminated soil is much higher over a wide range of pH levels. Furthermore, the superconducting magnetic separation was applied to feirritization-treated soil with magnetite. It is suggested that the combination of ferritization treatment and magnetic separation may be one of the techniques for the remediation of contaminated soil containing heavy metals.
