Efficient soluble anionic dye removal and antimicrobial properties of ZnO embedded‐ Polyphenylsulfone membrane

Abstract

As a result of the involvement of pollutants in water, there is the need to develop a facile and effective membrane technology that can not only treat dyes, but also kill bacteria in wastewater. In this work, a facile strategy is proposed for the preparation of a nanostructured hybrid membrane based on Polyphenylsulfone containing different ZnO nanoparticle contents. The results confirm that ZnO nanoparticle plays a key role in achieving the efficient removal of soluble anionic dyes from aqueous solution. The optimal membrane exhibits excellent dye rejection approximately 98% with impeccable water flux 19 L/m2h; and exhibits antifouling properties, presenting dye‐fouled flux recovery ratio> 90%. Moreover, an investigation of antibacterial properties of the material showed that the nanostructured hybrid membrane has good antibacterial properties (nearly 6.2 and 6.8) against both Escherichia coli and Staphylococcus aureus. Therefore, the proposed nanostructured hybrid membrane may provide an efficient for treating dye and bacteria in wastewater.

Recent Advancements in Polyphenylsulfone Membrane Modification Methods for Separation Applications

“…The nanocomposite membrane reduced biofouling abilities and better water fluxes. The possi-bility of bacterial attachment (biofouling) was associated with water transport and surface characteristics [87,95,104]. The casting solution composition, concentration, and inorganic salts all had an impact on the membrane filtration efficiency.…”

The Application of Polymer Inclusion Membranes for the Removal of Emerging Contaminants and Synthetic Dyes from Aqueous Solutions—A Mini Review

“…In recent years, there has been increased interest in the possibility of using various types of membranes to remove ECs and synthetic dyes from wastewater. In principle, membrane-based processes are considered more environmentally friendly than many traditional methods of removing these pollutants [ 21 , 22 ]. One type of liquid membranes (LMs) are polymer inclusion membranes, containing a polymer matrix, carrier, and most often a plasticizer, the use of which enables simultaneous extraction and re-extraction.…”

Development of High Flux Nanocomposite Polyphenylsulfone/Oxidized Multiwalled Carbon Nanotubes Membranes for Ultrafiltration Using the Systems with Critical Solution Temperatures

“…These advantages result in using PPSU membranes in ultrafiltration [ 7 , 8 , 9 ], nanofiltration [ 10 , 11 , 12 , 13 ], forward osmosis [ 14 ], pervaporation [ 15 , 16 , 17 ], and gas separation [ 16 , 18 , 19 ], in membrane contactors [ 20 ] and proton exchange membrane fuel cells [ 21 ]. PPSU membranes were developed for water treatment [ 22 , 23 , 24 , 25 ], water desalination [ 14 , 26 ], for dye removal [ 3 , 21 , 27 , 28 , 29 ], oil in water separation [ 30 , 31 , 32 ], water purification from natural organic matter (NOM) [ 33 ], removal of heavy metal ions [ 10 , 34 ], CO 2 /CH 4 gas separation [ 18 ], removal of free fatty acid from crude palm oil [ 35 ], removal of kinetic hydrate inhibitor from water [ 36 , 37 ], the separation of biobutanol from ABE mixtures [ 5 ] and cumene from water via pervaporation [ 17 ].…”
