英国曼彻斯特大学研究人员4月3日在《自然·纳米技术》发表报告说,他们开发的一种新型石墨烯氧化物薄膜能更高效地过滤海水中的盐,未来在海水淡化产业中有非常好的应用前景。氧化石墨烯薄膜在气体分离和水处理方面已经展示了很大的应用潜力,但现有的这类薄膜还无法适应海水淡化工艺要求。曼彻斯特大学此前的研究发现,如果将这类薄膜浸泡在水中,它会轻微膨胀,微小的盐离子会随着水流渗透薄膜,无法完成对盐的过滤。
Researchers at the University of Manchester in the United Kingdom published a report on “Nature Nanotechnology” on April 3 that they have developed a new type of graphene oxide film that filters salt in seawater more efficiently and has a very good future in the seawater desalination industry The application prospects. Graphene oxide films have shown great potential for gas separation and water treatment, but the existing films do not yet meet the desalination process requirements. Earlier studies at the University of Manchester found that if these films were soaked in water they swelled slightly, and tiny salt ions penetrated the film with the water flow and did not filter the salt.
