Zinc zeolite imidazole framework material (ZIF-8) is suitable for uranium adsorption due to its high specific surface area and abundant active sites. Aiming at the problems of long time and large consumption of organic solvents in the synthesis of ZIF-8 by traditional solvent method, ZIF-8 was rapidly synthesized by green and efficient mechanochemical method using zinc hydroxide and 2-methylimidazole as raw materials and used for uranium adsorption. The results show that the ZIF-8 prepared by mechanochemical method has good crystallinity, rhombic dodecahedron morphology, specific surface area of 1 642 m2/g, and rich surface defects and active sites on the surface. Under suitable conditions, the removal rate of uranium by ZIF-8 is more than 99.99%, the maximum adsorption capacity is 476 mg/g, and the adsorption can reach equilibrium within 20 min. The process is a single-layer chemical adsorption mechanism. The cost analysis results show that the synthesis efficiency of mechanochemical method is 16 times higher than that of traditional solvent method, and former's theoretical material cost per gram of uranium is only 3.5% of that of the latter. The mechanism analysis results show that the high specific surface area of the material and the synergistic effect of hydroxyl groups and imidazole nitrogen atoms are the key to the efficient adsorption of U(Ⅵ). ZIF-8 prepared by rapid mechanochemical method has good performance and has certain application potential in the field of uranium adsorption.

锌沸石咪唑框架材料(ZIF-8)因比表面积高、活性位点丰富,适用于铀吸附。针对传统溶剂法合成ZIF-8存在耗时长、有机溶剂消耗大等问题,研究了以氢氧化锌和2-甲基咪唑为原料,采用绿色、高效的机械化学法快速合成ZIF-8并用于吸附铀。结果表明:机械化学法制备的ZIF-8结晶性好,呈菱形十二面体形貌,比表面积达1 642 m2/g,且表面存在丰富缺陷和活性位点;在适宜条件下,ZIF-8对铀的去除率超过99.99%,最大吸附容量为476 mg/g,吸附可在20 min内达到平衡,该过程为单层化学吸附机制。成本分析结果表明,机械化学法的合成效率较传统溶剂法提升16倍,前者处理每克铀的理论材料成本仅为后者的3.5%。机制分析结果表明,材料高比表面积及羟基与咪唑基的协同作用是铀酰离子高效吸附的关键。采用快速机械化学法制备的ZIF-8性能较好,在铀吸附领域具有一定应用潜力。

锌沸石咪唑框架材料(ZIF-8)因比表面积高、活性位点丰富,适用于铀吸附。针对传统溶剂法合成ZIF-8存在耗时长、有机溶剂消耗大等问题,研究了以氢氧化锌和2-甲基咪唑为原料,采用绿色、高效的机械化学法快速合成ZIF-8并用于吸附铀。结果表明:机械化学法制备的ZIF-8结晶性好,呈菱形十二面体形貌,比表面积达1 642 m2/g,且表面存在丰富缺陷和活性位点;在适宜条件下,ZIF-8对铀的去除率超过99.99%,最大吸附容量为476 mg/g,吸附可在20 min内达到平衡,该过程为单层化学吸附机制。成本分析结果表明,机械化学法的合成效率较传统溶剂法提升16倍,前者处理每克铀的理论材料成本仅为后者的3.5%。机制分析结果表明,材料高比表面积及羟基与咪唑基的协同作用是铀酰离子高效吸附的关键。采用快速机械化学法制备的ZIF-8性能较好,在铀吸附领域具有一定应用潜力。

Zinc zeolite imidazole framework material (ZIF-8) is suitable for uranium adsorption due to its high specific surface area and abundant active sites. Aiming at the problems of long time and large consumption of organic solvents in the synthesis of ZIF-8 by traditional solvent method, ZIF-8 was rapidly synthesized by green and efficient mechanochemical method using zinc hydroxide and 2-methylimidazole as raw materials and used for uranium adsorption. The results show that the ZIF-8 prepared by mechanochemical method has good crystallinity, rhombic dodecahedron morphology, specific surface area of 1 642 m2/g, and rich surface defects and active sites on the surface. Under suitable conditions, the removal rate of uranium by ZIF-8 is more than 99.99%, the maximum adsorption capacity is 476 mg/g, and the adsorption can reach equilibrium within 20 min. The process is a single-layer chemical adsorption mechanism. The cost analysis results show that the synthesis efficiency of mechanochemical method is 16 times higher than that of traditional solvent method, and former's theoretical material cost per gram of uranium is only 3.5% of that of the latter. The mechanism analysis results show that the high specific surface area of the material and the synergistic effect of hydroxyl groups and imidazole nitrogen atoms are the key to the efficient adsorption of U(Ⅵ). ZIF-8 prepared by rapid mechanochemical method has good performance and has certain application potential in the field of uranium adsorption.
