Full Description
Enables readers to understand how to remove uranium from seawater and nuclear wastewater through a variety of techniques
Efficient Uranium Reduction Extraction provides experimental and theoretical knowledge on uranium reduction extraction, with information ranging from the design of extraction materials and methods to the evolution of uranium species and its reaction mechanism. Throughout the text, the authors illustrate the solution for the reductive separation of radioactive elements in complex environments and provide a new pathway for the treatment of wastewater.
Written by a team of highly qualified authors, Efficient Uranium Reduction Extraction includes information on:
General chemical properties of uranium, including its coordination structure and valence state transformations
Performance evaluation criteria and device integration for uranium reduction and extraction
Methods including nano-zero-valent iron, commercial iron powder under the influence of external fields, carbon-semiconductor hybrid materials, and plasma
Advanced techniques, such as atomic-resolved HAADF-STEM and synchrotron XAFS, which explore uranium reduction at the atomic level
Efficient Uranium Reduction Extraction delivers important and unique guidance on the subject for chemists, material scientists, and environmental scientists in universities and research institutions worldwide, along with undergraduate and postgraduate students in related programs of study.
