“…The GO materials with hydrophobicity and anti-biofouling enhancement have fine antifouling properties, and are widely applied in water treatment. 76 There are mainly three different pollution forms on the surface of materials, including inorganic pollution, organic pollution and biological pollution. 77 The hydrophobicity and protein resistance exerted their effects in cooperation for the antifouling property.…”

“…GO exhibits excellent chemical and mechanical stability and a large specific surface area [20][21][22]. Owing to these exceptional features, GO is currently being exploited as a superficial filler in polymeric membranes [23]. Due to its thinner structure, robust chemical and mechanical action, and effective ion-selective properties, graphene oxide holds the advantage of being a new generation material in wastewater treatment [24][25][26].…”

Photocatalysis is an efficient and an eco-friendly way to eliminate organic pollutants from wastewater and filtration media. The major dilemma coupled with conventional membrane technology in wastewater remediation is fouling. In this study, the photocatalytic degradation potential of novel thermoplastic polyurethane (TPU) based NiO on aminated graphene oxide (NH2-GO) nanocomposite membranes was explored. The fabrication of TPU-NiO/NH2-GO membranes was achieved by the phase inversion method and analyzed for their performances. The membranes were effectively characterized in terms of surface morphology, functional group, and crystalline phase identification, using scanning electron microscopy, Fourier transformed infrared spectroscopy, and X-ray diffraction analysis, respectively. The prepared materials were investigated in terms of photocatalytic degradation potential against selected pollutants. Approximately 94% dye removal efficiency was observed under optimized conditions (i.e., reaction time = 180 min, pH 3–4, photocatalyst dose = 80 mg/100 mL, and oxidant dose = 10 mM). The optimized membranes possessed effective pure water flux and excellent dye rejection (approximately 94%) under 4 bar pressure. The nickel leaching in the treated wastewater sample was determined using inductively coupled plasma-optical emission spectrometry (ICP-OES). The obtained data was kinetically analyzed using first- and second-order reaction kinetic models. A first-order kinetic study was suited for the present study. Besides, the proposed membranes provided excellent photocatalytic ability up to six reusability cycles. The combination of TPU and NH2-GO provided effective strength to membranes and the immobilization of NiO nanoparticles improved the photocatalytic behavior.

“…8,9 The most economically viable and therefore industrially applied methods for wastewater treatment are based on the adsorption techniques, usually in the form of membranes employed in desalination or chemisorption setups. [10][11][12][13][14] Over many years, researchers have explored the effectiveness of various adsorbents in these processes, including activated carbon (AC), zeolites, covalent organic frameworks (COFs), polymers, biosorbents, and other low-cost materials. [15][16][17][18][19][20][21][22][23][24][25][26][27] However, practical application of these systems is limited due to low adsorption capacities, problematic separation and poor recyclability, yielding an overall limited effectiveness.…”
