The effect of erbium (III) molybdate (Er₂MoO₆) nanomaterial as a new nanofiller on fabrication of polyethersulfone (PES) mixed matrix membranes was examined in terms of membrane morphology, hydrophilicity, permeability, mechanical strength, dye and protein separation and antifouling property. The synthesized Er₂MoO₆ nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The morphology and surface properties of the prepared nanocomposite membranes were evaluated by SEM images, surface roughness parameters using atomic force microscopy (AFM) and contact angle measurement. The pure water flux of the nanocomposite membranes improved significantly (195.3 L/m² h at 3 bar for 1 wt.%) after adding of Er₂MoO₆ due to the higher hydrophilicity in comparison with bare one (82.5 L/m² h). The fouling resistance results exhibited that 1 wt% Er₂MoO₆ blended membrane had the best antifouling characteristic (flux recover ratio of 87.6%). Evaluation of membrane separation performance was performed by examining the Reactive Red 195 rejection. The dye rejection data showed that the Er₂MoO₆/PES membranes have better dye removal capacity rather than the unfilled PES. It could be say that the Er₂MoO₆ nanocomposite membranes showed the suitable antibiofouling properties tested by BSA filtration due to low surface roughness and high hydrophilicity prompted by the blended nanomaterial.

从膜的形貌，亲水性，渗透性，机械强度，染料和蛋白质分离以及防污性等方面研究了钼酸III（Er ₂ MoO ₆）纳米材料作为新型纳米填料对聚醚砜（PES）混合基质膜的制备的影响。属性。合成的Er ₂ MoO ₆通过X射线衍射（XRD），傅里叶变换红外（FTIR）光谱和扫描电子显微镜（SEM）表征纳米颗粒。通过SEM图像，使用原子力显微镜（AFM）的表面粗糙度参数和接触角测量来评估所制备的纳米复合膜的形态和表面性质。加入Er ₂ MoO ₆后，纳米复合膜的纯净水通量显着提高（在3 bar，1 wt。％时为195.3 L / m ² h），因为与裸露的相比，亲水性更高（82.5 L / m ² h ）。耐污染性结果表明，Er ₂ MoO _6为1重量％混合膜具有最佳的防污性能（通量回收率为87.6％）。膜分离性能的评估是通过检查活性红195排斥反应来进行的。染料排斥数据表明，Er ₂ MoO ₆ / PES膜比未填充的PES具有更好的染料去除能力。可以说，由于掺混纳米材料的低表面粗糙度和高亲水性，Er ₂ MoO ₆纳米复合膜显示出通过BSA过滤测试的合适的抗污垢性能。
