Novel dense and supported (polyacrylonitrile substrate) mixed matrix membranes based on biopolymer sodium alginate (SA), modified by Zr-MOFs were developed to improve pervaporation dehydration properties of a parent SA membrane. The following Zr-MOFs were synthesized and tested as modifiers: unmodified UiO-66 and modified UiO-66(NH₂)-AcOH and UiO-66(NH₂)-EDTA. Two kinds of mixed matrix membranes were developed: without additional treatment and cross-linked with calcium chloride. The synthesized Zr-MOFs nanoparticles and developed SA and SA-Zr-MOFs membranes were studied using Fourier-transform infrared spectroscopy, nuclear magnetic resonance, scanning electron microscopy, surface area measurement, atomic force microscopy, X-ray diffraction analysis, thermogravimetric analysis, and swelling experiments. Dense and supported membranes were tested for their transport properties in the pervaporation dehydration of isopropanol (12, 30 wt% water for the untreated membranes and 12–100 wt% water for the cross-linked membranes). The best transport properties (dehydration of water/isopropanol mixtures at 22 °C) were demonstrated by a supported cross-linked membrane, containing 15 wt% of UiO-66: permeation flux 0.47–3.38 kg/(m²h), water content in permeate 99.9-97.5 wt%.

基于Zr-MOFs改性的基于生物聚合物藻酸钠（SA）的新型致密和支撑（聚丙烯腈底物）混合基质膜已被开发出来，以改善母体SA膜的全蒸发脱水性能。合成了以下Zr-MOF，并作为改性剂进行了测试：未改性的UiO-66和改性的UiO-66（NH ₂）-AcOH和UiO-66（NH ₂）-EDTA。开发了两种混合基质膜：无需额外处理，并与氯化钙交联。使用傅立叶变换红外光谱，核磁共振，扫描电子显微镜，表面积测量，原子力显微镜，X射线衍射分析，热重分析，热重分析研究了合成的Zr-MOFs纳米颗粒和SA和SA-Zr-MOFs膜的开发。和膨胀实验。测试了致密和支撑膜在异丙醇全蒸发脱水中的传输性能（未处理的膜为12、30 wt％的水，交联的膜为12–100 wt％的水）。载有15％（重量）的UiO-66的支撑的交联膜证明了最佳的运输性能（水/异丙醇混合物在22°C时的脱水）：² h），渗透液中的水含量为99.9-97.5 wt％。
