A novel multifunctional metal-organic frameworks (MOFs) [email protected]₃O₄@UiO-66 (UiO=University of Oslo) was fabricated to adsorb pharmaceuticals and personal care products (PPCPs) under near neutral conditions. We designed a wrinkle structure on the surface of [email protected]₃O₄@UiO-66 by seeded growth strategy. These wrinkles were composed of Fe₃O₄ nanoparticles and outermost UiO-66. It made the specific surface area of the MOFs increases, and provided multiple active sites for a representative pollutant salicylic acid (SA) adsorption. Moreover, lattice defects formed during secondary growth facilitating the coordination interaction between SA and the secondary building unit of [email protected]₃O₄@UiO-66 under near neutral conditions. These advantages made the adsorption capacity of per unit mass UiO-66 in [email protected]₃O₄@UiO-66 about 42% higher than that of the pristine UiO-66, and the removal rate of 1 mg L^-1 SA reach 64.5% in real wastewater. Furthermore, magnetic Fe₃O₄ particles in the wrinkles exhibited outstanding magnetic separation performance. So that [email protected]₃O₄@UiO-66 can be effectively separated from the liquid media and regenerated after adsorption. The results show that the wrinkled MOFs could be used as an excellent candidate for SA adsorption in real wastewater. More importantly, this strategy could guide the preparation of different kind of MOFs to adsorb PPCPs in wastewater.

一种新型的多功能金属有机骨架（MOFs）[电子邮件保护] ₃ O ₄ @ UiO-66（UiO =奥斯陆大学）被制造出来，以在接近中性的条件下吸附药物和个人护理产品（PPCP）。我们通过种子生长策略在[电子邮件保护的] ₃ O ₄ @ UiO-66的表面设计了皱纹结构。这些皱纹由Fe ₃ O _4组成纳米颗粒和最外层的UiO-66。它使MOF的比表面积增加，并为代表性的污染物水杨酸（SA）吸附提供了多个活性位。此外，在二次生长过程中形成的晶格缺陷促进了SA和[电子邮件保护] ₃ O ₄ @ UiO-66的二次构建单元之间在近中性条件下的协同相互作用。这些优点使得单位质量的UiO-66在[电子邮件保护] ₃ O ₄ @ UiO-66中的吸附能力比原始UiO-66高约42％，去除率达到1 mg L ^-1 SA实际废水中占64.5％。此外，磁性Fe ₃ O ₄皱纹中的颗粒表现出出色的磁分离性能。这样[电子邮件保护的] ₃ O ₄ @ UiO-66可以有效地从液体介质中分离出来，并在吸附后再生。结果表明，起皱的MOFs可以作为实际废水中SA吸附的极好候选者。更重要的是，该策略可以指导制备不同种类的MOF，以吸附废水中的PPCP。
