Progress of novel adsorbent materials in the treatment of uranium-containing wastewater

How to deal with radioactive uranium contamination in the water environment from nuclear power and mining processes is an urgent problem to be solved. Adsorption materials have become a major way to treat uranium-containing wastewater because of their large specific surface area, low cost, simple preparation and high adsorption capacity. This paper firstly compares the advantages and disadvantages of existing methods and different adsorption materials for the treatment of uranium-containing wastewater; secondly, the theoretical basis of adsorption materials such as adsorption phenomena and adsorption mechanisms are described; then the current research status of new adsorption materials such as new magnetic nano-, kaiamine oxime, polymer fibers, new metal-organic skeletal materials, biochar, microorganisms, etc. is analyzed, and the adsorption properties of these materials are summarized in terms of material characteristics, adsorption performance and application potential; finally, the adsorption properties of these materials are summarized in terms of their specificity, adsorption performance and application potential. Finally, the research directions for the treatment of uranium-depleted wastewater are presented from the perspectives of application, avoiding secondary pollution, and focusing on decontamination performance.
