Abstract

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.

聚丙烯酰胺改性掺氮碳作为电吸附废水中铀的高性能电极
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。
