Rapid vitrification of simulated Sr2+ radioactive contaminated soil for nuclear emergencies
- 34 Downloads
To efficiently inhibit the diffusion of radioactive nuclides in soil that were left by nuclear emergency accidents, microwave sintering technology was used in this work to vitrify the simulated strontium contaminated soil. Four kinds of simulated strontium-contaminated soil could be successfully vitrified almost completely within 30 min without any additional components. Sr2+ cations are immobilized into aluminosilicate glass network structure. In addition, the solubility of SrSO4 in different soil is related to the element contents of aluminum and silicon. This work reveals a demonstration that beta-radioactive contaminated soil could be treated by microwave vitrifying.
