摘要:
钕(Nd)是钕磁铁的关键部分,从稀土永磁体中分离Nd已经引起了广泛的关注。通过双模板导向离子印迹(DTD-OII)法,加入氧化石墨烯水溶液,制备出一种新型自撑式离子印迹氧化石墨烯复合膜(IGOMs)。与传统印迹方法相比,该方法不需要额外步骤,显著提高印迹效率的同时,制备出的自撑式复合膜还表现出固-液萃取对Nd3+选择性吸附性能。实验结果表明:在pH=4.0时,IGOMs的Nd3+最大吸附量为27.27 mg/g。此外,石墨烯的掺杂可以有效提高复合膜柔性和稳定性,使其在工业应用上成为可能。
Abstract:
Neodymium(Nd)is a critical component of neodymium magnets and the separation of Nd from rare-earth permanent magnets has attracted widespread attention. Free-standing ionic imprinted graphene oxide composite films(IGOMs)were prepared by dual-template docking oriented ionic imprinting(DTD-OII)method and adding graphene oxide aqueous solution. Compared with conventional imprinting methods, this novel method does not need extra steps, but significantly advance imprinted efficiency. Besides, the free-standing composite films exhibit excellent selective adsorption of Nd3+ by solid-liquid extraction. The eperimental results show that the maximum adsorption capacity of Nd3+ for IGOMs is 27.27 mg·g-1 under pH=4.0. In addition, the incorporated graphene can effectively improve the flexibility and stability of films, making it possible for industrial application.
