摘要:
Background Efficient separation of Re from molybdenum and uranium ores holds significant implications for resource utilization and environmental conservation. Efficient separation of Re from molybdenum and uranium ores holds significant implications for resource utilization and environmental conservation. Methods A novel quaternary phosphonium (PPh 3 ) modified cellulose (CMS-g-VBPPh 3 NO 3 ) was synthesized through the halogenation reaction between PPh 3 and the VBC grafted cellulose intermediate (CMS-g-VBC). The recovery of Re was evaluated by batch and dynamic adsorption experiments. A nove...
