A composite material that comprised metal-organic nanotubes (MONTs) and a sponge, Cu-MONTs-sponge, was synthesized by using a rapid and convenient surfactant-assisted dip-coating method and used as a high-performance adsorbent for the solid-phase extraction of pharmaceuticals and personal care products (PPCP) from environmental water samples. By adjusting the surfactant concentration, a composite material that contained metal-organic nanotubes and a macroporous 3D porous sponge was constructed. This modified sponge achieved outstanding reproducibility as an adsorbent, with the adsorption of trace or ultratrace amounts of contaminants. Moreover, this composite material was conveniently recycled and its extraction efficiency only decreased by 6.3-12.1 % after 30 adsorption/desorption cycles. The resulting composite exhibited excellent adsorption capacity for PPCPs, which was attributed to its unique porous structure, natural hydrophobicity, and electrostatic interactions between the metal-organic nanotubes and analyte molecules. This Cu-MONTs-sponge material is an ideal adsorbent for the extraction of trace amounts of PPCPs from environmental water samples.
一种由金属有机纳米管（MONTs）和海绵组成的复合材料，Cu-MONTs-海绵，通过快速简便的表面活性剂辅助浸涂法合成，并用作从环境水样中萃取药物和个人护理产品（PPCP）的高性能固相萃取剂。通过调整表面活性剂浓度，构建了一种包含金属有机纳米管和大孔 3D 多孔海绵的复合材料。这种改良后的海绵作为吸附剂具有出色的重现性，可吸附痕量或超痕量的污染物。此外，这种复合材料方便回收，经过 30 次吸附/解吸循环后，其萃取效率仅下降 6.3-12.1%。该复合材料对 PPCPs 具有优异的吸附能力，这归因于其独特的多孔结构、天然疏水性以及金属有机纳米管和分析物分子之间的静电相互作用。这种 Cu-MONTs-海绵材料是从环境水样中萃取痕量 PPCP 的理想吸附剂。
