Abstract

Seawater Desalination uses hydrophobic membranes. Many techniques have been developed to improve membrane hydrophobicity by depositing particles on the membrane surface. In this study, a nanocomposite membrane utilizing Triethylenetetramine (TETA) is suggested. The membrane incorporates Multiwalled Carbon Nanotubes (MWCNT) in conjunction with Triethylenetetramine Dihydrochloride (TETA-DH). In water bath, different percentages of TETA-DH films are formed. Electro-spin fabrication of MWCNTs using TETA-DH yields smooth, low-pore membranes. Membranes and their characteristics are identified by contact angle, layer thickness, and conductivity measurements. Membrane performance is examined for heat flux and salt rejection. Compared to commercial membranes, the proposed membrane exhibits superior antifouling and anti-wetting features. The membrane exhibited permeation and rejection ratio of 46 Kg m2 h−1 and 99.99% respectively which is superior as compared with other membranes. The hydrophilic Surface Modifying Macromolecules percentage (LSMM%) is evaluated because it depends on average pore size, hydrophobicity, surface porosity, and shape. The tests demonstrate the excellent performance of the proposed membrane for controlling membrane fouling.

用三乙烯四胺二盐酸盐 (TETA-DH) 和多壁碳纳米管 (MWCNT) 制备用于海水淡化的纳米膜

海水淡化使用疏水膜。人们开发了许多技术，通过在膜表面沉积颗粒来改善膜的疏水性。本研究提出了一种利用三乙烯四胺（TETA）的纳米复合膜。该膜将多壁碳纳米管（MWCNT）与三乙烯四胺二盐酸盐（TETA-DH）结合在一起。在水浴中可形成不同比例的 TETA-DH 膜。使用 TETA-DH 对 MWCNTs 进行电旋制造，可获得光滑、低孔隙的薄膜。通过接触角、膜层厚度和电导率测量来确定膜及其特性。通过热通量和盐分排斥来检验膜的性能。与商用膜相比，所提出的膜具有更好的防污和防湿特性。膜的渗透率和排盐率分别为 46 Kg m2 h-1 和 99.99%，比其他膜更优越。对亲水性表面改性大分子百分比（LSMM%）进行了评估，因为它取决于平均孔径、疏水性、表面孔隙率和形状。测试表明，拟议的膜在控制膜污垢方面具有卓越的性能。
