“…GO shows a broad and strong peak in the region around ~3700 to 3000 cm −1 and 1634 cm −1 , which is due to the stretching and bending of hydroxyl (O─H) group. The appearance of this group might be from absorbed water, O─H from carboxylic groups or phenolic O─H . Ample oxygen‐containing functional groups found in GO indicates that the graphite powder was successfully oxidized using modified Hummer's method .…”

BACKGROUND In this work, a series of graphene oxide–polyethersulfone (GO–PES) composite flat sheet (FS) and hollow fiber (HF) membranes were fabricated by blending 0.5 and 1.0 wt% of GO into the PES matrix and utilized for oil–water separation. GO was first prepared and characterized by using Fourier‐transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X‐ray diffraction (XRD) and thermogravimetric analysis (TGA) before being used as membrane fillers. RESULTS Interestingly, although similar dope composition was used for the fabrication of HF and FS membranes, their morphology and pore size varied significantly owing to the way the membranes were fabricated. Significant enhancement of hydrophilicity was observed for both composite FS and HF membranes, where the water contact angle value decreased from 74.8° to 42.2° and 71.4° to 49.8°, respectively. The flux of the composite membranes increased up to 150% of the bare membranes especially when 1.0 wt% of GO was added. Although higher oil rejection (~99%) was observed for HF membranes that possess smaller pores, the permeation flux was maintained due to the improved flow dynamic. Lower oil rejection (up to 50%) was observed for FS membranes, which might be due to its big pore sizes particularly at the bottom surface. As more oil droplets formed on the membrane surface and prevented water molecules to pass through the membrane, fouling might occur rapidly. CONCLUSIONS The results obtained in this work suggest that surface hydrophilicity, pore size of membranes and oil–water separation performances was greatly affected by membrane shape. Owing to many advantages of HF membranes, this type of membrane has great potential for commercial applications. © 2020 Society of Chemical Industry

“…Thus, incorporation of TiO 2 /HNTs has improved the antifouling behaviour of membrane through decreasing BSA accumulation on the surface of PA selective layer. It can be stated that interplay of surface hydrophilicity and surface electrostatic interactions are the two main parameters responsible for membrane anti-fouling behaviour [57,58].…”

With increasing industrial activities around the globe, water source had been severely polluted by various heavy metal substances that lead to adverse effect not only to the environment but also to human being. The content of heavy metal in wastewater especially cadmium was increasing in the recent years and can be attributed to the strong demand of cadmium in the battery and electroplating industry. In this study, the potential of novel nanocomposite mixed matrix membrane incorporated with manganese oxide (MnO 2 ) nanoparticle for cadmium removal was investigated. The membranes were fabricated using polyethersulfone (PES) by phase inversion technique with different manganese oxide nanoparticle loading. Prior to performance evaluation, the membranes were characterized by their structural morphology, surface chemistry and cadmium adsorption capability. The results suggested that PES membrane incorporated with 2.0 ratio of MnO 2 /PES exhibited the best result in both cadmium adsorption (51.7 mg/g) and water permeability (1462 L/m 2 .h.bar). This indicated the prospect of this membrane to be applied in wastewater treatment industry.Keywords: mixed matrix membrane, polyethersulfone, cadmium, wastewater Abstrak Sumber air di seluruh dunia telah teruk tercemar dengan pelbagai bahan logam berat yang akan memberi kesan buruk kepada alam sekitar dan manusia. Pencemaran air ini adalah akibat daripada aktiviti-aktiviti perindustrian yang semakin pesat di dunia kita. Kandungan logam berat dalam air sisa terutamanya kadmium semakin meningkat dalam beberapa tahun ini disebabkan oleh permintaan kadmium yang tinggi terutamanya dalam industri bateri dan elektropenyaduran. Dalam kajian ini, potensi membran campuran matrik yang baharu dengan mangan oksida (MnO 2 ) dikajikan dalam sistem turas aliran lintang untuk penyingkiran kadmium. Membran ini dibuat daripada polietersulfona (PES) dengan teknik fasa berbalik dengan pelbagai berat zarah nano mangan oksida. Sebelum kajian dijalankan, membran dicirikan dengan kajian struktur dan permukaan morfologi, keliangan, sudut kenalan permukaan, kajian pembenaman MnO 2 dan kajian penjerapan kadmium. Hasil kerja kajian ini mencadangkan bahawa membran PES dengan nisbah 2.0 MnO 2 menunjukkan keputusan yang memberangsangkan dalam penjerapan kadmium (51.7 mg/g) dan fluks air tulen yang paling tinggi (1,462 L/m 2 .h.bar). Keputusan kajian ini telah menunjukkan membran mempunyai potensi yang besar digunakan dalam industri rawatan air sisa.Kata kunci: membran matriks campuran, polietersulfon, kadmium, air sisa
