| 英文摘要 | To solve the issues of energy shortage and environmental pollution, the extraction of U(VI) from wastewater is of great interest and challenge. Herein, we demonstrate a super-efficient and high-selective method to extract U(VI) from wastewater in a weak acid environment (pH 3.0 similar to 6.0) by a dual-functional extractant of Na2V6O16 center dot 2H(2)O (NVO) nanobelts. The soluble U(VI) was immobilized by NVO nanobelts through a chemical reaction combined with complexations (induced by electrostatic attraction). Benefiting from such processes, the extraction rate can be over 93% and the extraction capacity can reach 930.0 mg/g when the initial concentration of U(VI) is 100.0 mg/L at 45 degrees C, and the extraction rate of U(VI) only declines by 3% even at high CO32- concentration (10 mM) compared to that without CO32- at pH 4.0. The present work demonstrates a new way toward the highly efficient and selective U(VI) extraction from wastewater, which may have great application potential in U(VI) extraction and environmental pollution control. |
