MXene, a new 2D transition metal carbide-based material, is gaining outstanding attention in recent days in the area of separation and purification. In this study, we have successfully synthesized vanadium-based MXene-V2CTx (where T represents functional groups such as –OH, O, and F) by etching an aluminum layer from V2AlC. For the first time, a vanadium-based MXene-V2CTx-embedded mixed matrix membrane was fabricated and utilized for removal of hazardous dye and humic acid from wastewater. With an increase in V2CTx loading, the hydrophilicity of the polyphenylsulfone (PPSU) membrane reasonably improved, and its water contact angle was reduced from 82.8 to 70.9°. V2CTx nanosheet-embedded PPSU membrane exhibited an excellent pure water permeability of 247 L m–2 h–1, which was 266% elevated than the pristine PPSU membrane. The V2CTx-PPSU membrane revealed a good antifouling nature, thermal stability, and 98.5% removal of humic acid. The optimal membrane exhibited 96.6 and 82.02% expulsion of Reactive Black 5 (RB 5) dye and Reactive Orange 16 (RO 16) dye, respectively. The flux for RO 16 and RB 5 dyes and humic acid were remarkable with a value of 202.02, 161.61, and 141.41 L m–2 h–1, respectively. This work provides a new V2CTx-incorporated PPSU ultrafiltration membrane to effectively treat humic acid and dye wastewater.

二维钒 MXene 聚苯砜超滤膜的制备，用于提高水通量并有效分离废水中的腐殖酸和染料
MXene是一种新型二维过渡金属碳化物基材料，近年来在分离和纯化领域受到广泛关注。在这项研究中，我们通过蚀刻 V 2 AlC 铝层成功合成了钒基 MXene-V 2 CT x （其中 T 代表 -OH、O 和 F 等官能团）。首次制备了钒基 MXene-V 2 CT x嵌入混合基质膜并用于去除废水中的有害染料和腐殖酸。随着V 2 CT x负载量的增加，聚苯砜（PPSU）膜的亲水性得到合理改善，其水接触角从82.8°降低至70.9°。 V 2 CT x纳米片嵌入的 PPSU 膜表现出优异的纯水渗透性，为 247 L m –2 h –1，比原始 PPSU 膜提高了 266%。 V 2 CT x -PPSU膜具有良好的防污性、热稳定性和腐殖酸去除率98.5%。最佳膜对活性黑 5 (RB 5) 染料和活性橙 16 (RO 16) 染料的排出率分别为 96.6% 和 82.02%。 RO 16 和RB 5 染料以及腐植酸的通量非常显着，分别为202.02、161.61 和141.41 L m –2 h –1 。这项工作提供了一种新型的V 2 CT x掺入PPSU超滤膜来有效处理腐殖酸和染料废水。
