“…Fourier Transform Infrared Spectroscopy (FTIR) is a powerful technique for analyzing chemical structures and identifying functional groups present on membrane surfaces [37]. FTIR spectra of BP-NPs, PLA/PBAT, and modified membranes containing 0.05 wt.% banana peel powder were collected within the spectrum ranging from 4000 cm −1 to 500 cm −1 .…”

Ultrafiltration membranes are often considered a highly efficient technique for purifying oily wastewater. The primary objective of this research was to improve the performance and antifouling properties of PLA/PBAT membranes used in oily wastewater treatment by incorporating banana peel (BP) nanoparticles. Various characterization techniques, including field emission scanning electron microscopy (FESEM), wettability analysis, pure water flux measurement, porosity assessment, tensile analysis, and FTIR analysis, were employed to describe the prepared membranes. The results of the FT-IR test revealed that BP nanoparticles were effectively integrated into the PLA/PBAT membrane matrix. The contact angle decreased from 73.7° for the pristine PLA/PBAT membrane to 38.99° for the membrane incorporating 0.05 wt.% BP-NPs, indicating that the nanoparticles enhanced the hydrophilic characteristics of the membranes. A similar trend was observed for the pure water flux of PLA/PBAT/BP membranes, suggesting that membranes with a BP-NP concentration of 0.05 weight percent exhibited the highest pure water flux. This improvement can be attributed to the synergistic effects of the nanoparticles. Additionally, the presence of BP-NPs enhanced the mechanical properties of the membranes. Finally, an ultrafiltration system using oily wastewater as feed was employed to evaluate the performance of the prepared membranes. The finding demonstrated that PLA/PBAT/BP membranes exhibited a higher flux and a greater oil removal efficiency of 105.3 L/m2h and 95.2% compared to neat PLA/PBAT membranes (62 L/m2h and 88%), respectively.

“…This technique gives valuable data about melting temperature (T m ) glass transition temperature (T g ), and crystallization temperature (T c ) of various polymer types. 152,153 For instance, using TGA to examine the thermal stability of TFC and TFN membranes revealed that the distribution of TiO 2 NPs within the TFN membrane, produced a slightly higher onset temperature for intense degradation compared to the unmodied TFC membrane. 127 Namely, the onset degradation temperature increased from 530 to 550 °C upon the incorporation of TiO 2 NPs.…”

“…Another strategy is based on the preparation of blended polymer membranes. Cellulose acetate was blended with natural and synthetic polymers such as chitosan [59], carboxymethyl cellulose [60], polyethersulfone [61], polyvinyl alcohol [62], polyethylene glycol [63] or polyurethane [64], in all cases a positive influence in membrane antifouling performances being observed.…”

Water, one of the most important resources that the planet offers us, cannot be used without meeting certain quality parameters which are increasingly difficult to achieve due to human activities such as deforestation, improper industrial and agricultural waste management, maritime traffic and fuel spillages. Cellulose-based materials or membranes are among the most important candidates to water treatment processes in the actual context of sustainable processes due to the chemical versatility of this cellulose derivative and also due to its large availability This review aims to present the use of functionalized or composite cellulose acetate membranes in water reuse processes in the context of the circular economy. The synthesis methods, process performances, and limitations of these membranes are presented, and the main future directions are thoroughly discussed at the end of the manuscript.
