Photodegradation of Bisphenol a in Water via Round-the-Clock Visible Light Driven Dual Layer Hollow Fiber Membrane

Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC) that can cause adverse effects on human health. The incorporation of materials as visible light photocatalysts and its energy storage capability allow for the photodegradation BPA, especially in absence a source. To date, there have been no significant studies regarding membrane technology, with only focus suspension form. Hence, this study was conducted to degrade pollutant through co-extrusion process using mixture copper (II) oxide tungsten photocatalyst materials, respectively. Both were embedded into polyvinylidene (PVDF) membranes produce Cu2O/WO3/PVDF dual-layer hollow fiber (DLHF) membrane. outer dope extrusion flow rate set at 3 mL/min, 6 9 mL/min photocatalyst:polymer ratios 0.3, 0.50, 0.7 Cu2O/WO3/PVDF, performance each ratio evaluated 2 ppm BPA irradiation. results showed membrane’s inner layers featured finger-like void structures, while intermediate part had sponge-like structure. 0.5 hydrophilic high porosity 54.97%, resulting 510 L/m2h. Under irradiation, Cu2O/PVDF DLHF 6-mL/min able remove 97.82% 2-ppm without leaching water sample. dark conditions, sample could drive certain degradation after lighting off up 70.73% BPA. photocatalytic most optimal due potential morphology ability large amount It important emphasize usage provide contribution toward more practical membranes, so occur even conditions.
