Areas of Research Interests/ Research Projects
Prof. Xu’s research interests mainly focus on nuclear chemistry and radiochemistry, including actinide chemistry, radiochemical separation, and environmental radiochemistry.
Actinide Chemistry
Coordination chemistry and redox chemistry of actinides, especially those transuranic elements such as Np, Pu, Am, with emphasis on oxidation state control, speciation identification and thermodynamic exploration.
Radiochemical Separation
Developing techniques for radioactive nuclides separation based on solvent extraction and ion exchange. Developing processes for High Level Liquid Waste partitioning.
Environmental Radiochemistry
Understanding the speciation and migration behavior of radionuclides in aquatic environment.
Research Status
Recent research projects include:
202401 – 202812 Actinide radiochemistry, National Science Fund for Distinguished Young Scholars
202010 – 202312 Chemical behavior and separation mechanism of transuranic elements in nuclear waste management, Natural Science Foundation of Beijing Municipal for Distinguished Young Scholars
