Advances in Research on Occurrence of Uranium in Soil and Radioactive Pollution Control
Uranium is a special heavy metal with radioactivity. The occurrence form of uranium in soil directly affects its toxicity and the ability of migration and transformation to plants. Therefore
it is of great significance to study the occurrence forms of uranium for remediation and remediation of uranium contaminated soi. In order to study the existing forms of uranium in soil
the extraction methods of uranium from soil were discussed
and the chemical and biological remediation technologies of radioactive contaminated soil were summarized. The results showed that: compared with the advantages and disadvantages of Tessier method and BCR method
it is necessary to further optimize the continuous extraction method
establish a unified operation specification and extraction process
so as to make the extraction results comparable; previous studies on the chemical forms of uranium in soil mainly focused on the form distribution and ecological effectiveness of uranium in soil
and more qualitative studies were conducted
which made it difficult to improve uranium pollution in soil.Through the analysis of the principle
use conditions
advantages and disadvantages of different repair technologies
it is proposed that the comprehensive repair technology can solve the problems of single repair technology to a certain extent
so the discussion of composite repair technology will become the main direction of future.
