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