摘要

电吸附技术作为一种节能、简便的技术，在从水溶液中分离铀的过程中具有良好的潜力。本研究采用蔗糖和尿素一步碳化法制备掺氮炭，通过改性得到聚丙烯酰胺改性掺氮炭（PAM/NC）。电吸附测试结果表明，PAM/NC-2 的性能最好，最大电吸附容量为 619.5 mg g-1。经过 5 次吸附-解吸循环后，性能损失小于 20%。总体而言，这种材料在六（U）铀污染修复方面具有潜在的应用价值，满足了核能可持续发展的需要。

Polyacrylamide-modified nitrogen-doped carbon as a high-performance electrode for electrosorption of uranium from wastewater

As an energy-saving and facile technology, electrosorption technology has good potential in the process of separation of uranium from aqueous solution. In this study, sucrose and urea were used to prepare nitrogen-doped carbon by one-step carbonization, and polyacrylamide modified nitrogen doped carbon (PAM/NC) was obtained by modification. The electrosorption test results indicated that PAM/NC-2 had the best properties and the maximum electrosorption capacity was 619.5 mg g⁻¹. The performance loss was less than 20% after 5 adsorption–desorption cycles. Overall, this material had a potential application in U(VI) pollution remediation, meeting the need for sustainable development of nuclear energy.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
