Study on magnetic separation for decontamination of cesium

Sep 15, 2014· The accident of Fukushima Daiichi nuclear power plant caused the diffusion of radioactive cesium over the wide area. We examined the possibility of applying magnetic separation method using the superconducting magnet, which can process a large amount of the soil in high speed, to the soil decontamination and volume reduction of the radioactive cesium contaminated soil.

Magnetic separation for environmental remediation

Magnetic Separation is a physical separation process that segregates materials in a mixture on the basis of magnetic susceptibility. Most of the actinides and their compounds and fission products are paramagnetic, and most host materials such as water, graphite, soil, and sand are diamagnetic.

Soil Decontamination SpringerLink

In relation to the techniques, necessary soil preparation steps such as screening, magnetic separation and light fraction removal are introduced. Apart from the common techniques mentioned, the idea of phytoremediation is discussed, taking all relevant approaches such as phytoextraction and phytodegradation into account.

Study on Decontamination of Contaminated Soils by Magnetic

Oct 18, 2013· Abstract: In this paper, we examined a new method for decontamination of soils by magnetic separation to reduce the volume of contaminated soils. In this method, we separate paramagnetic 2:1 type clay minerals with strong adsorbility of Cs ions from diamagnetic 1:1 type clay minerals with weak adsorbility of Cs ions.

Enhanced selective separation of fine particles from Cs

Oct 03, 2020· In addition, we used the magnetic-sieving separation method to separate Cs-contaminated fine soil under acidic conditions: a decontamination efficiency of the treated soil of 58.5% was achieved by removing the highly contaminated fine soil fraction. The use of magnetic separation under acidic conditions was found to be highly effective for soil
