Synthesis and optimization of PES‐Fe₃O₄ mixed matrix nanocomposite membrane: Application studies in water purification

Abstract

A mixed matrix nanocomposite membrane comprising of polyethersulfone (PES) and nano Fe3O4 particles was synthesised with an aim to develop a membrane with superior ability to high water flux while maintaining salt rejection efficiency. The study focused on optimizing the effect of different percentages of nano Fe3O4 particles addition on the membrane pure water flux, and rejection of both the NaCl and MgSO4. The results showed that the PES nanocomposite membrane with 15% Fe3O4 exhibited the highest pure water flux, while the highest rejection of NaCl and MgSO4 belonged to the PES‐10% Fe3O4. The rejection sequence of PES‐10% Fe3O4 membrane was 68% and 82%, respectively. Also it was observed that nano Fe3O4 particles improved membrane hydrophilicity, and helped to construct a membrane with desire surface and cross‐section morphology. POLYM.

Block copolymer based novel magnetic mixed matrix membranes-magnetic modulation of water permeation by irreversible structural changes

“…The successful application of these nanocomposite membranes depends on the organic and inorganic components, as well as the chemical interaction between them. Previously various types of INPs such as MgO, TiO 2 , Fe 2 O 3 , and Fe 3 O 4 have been incorporated in the development of nanocomposite membranes [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

Engineering nanocomposite membranes: Addressing current challenges and future opportunities

“…There are a large number of studies that have used different ENMs in the development of novel composite polymer membranes for water treatment applications. The materials that have been studied include, graphene oxide (GO) [32,33], carbon nanotubes (CNTs) [34][35][36], Silver (Ag) [37,38], Titanium (TiO2) [39][40][41], Aluminium (Al2O3) [42], Silicon (SiO2) [22], Iron (Fe3O4) [43], Zirconium (ZrO2) [44] and Zinc (ZnO) [45], Clay nanoparticles [46] and Zeolite (NaX) [47,48]. However, the focus of this review is mainly on the modification of polymeric membranes using the diverse range of ENMs, this includes the features of ENMs, strategies of incorporation, influence of ENMs on polymeric membranes surface characteristics and antifouling properties and issues associated from incorporation of ENMs.…”
