Özet

In recent years, the reduction of water reserves has highlighted the processes related to obtaining high-quality water. For this aim, membrane processes have gained significant attention regarding sustainability and energy savings. In this study, the cross-flow filtration (CFF) process, as a green process, was used to remove tartrazine (E-102), an anionic dye, from aqueous solutions. For this aim, cellulose-supported alginate (Alg-CS), cellulose-supported alginate-aluminum oxide (Alg-CS/Al2O3), and cellulose-supported alginate-graphite (Alg-CS/C) composite membranes were prepared. Characterization of the membranes was performed using differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and contact angle (CA) measurements. The effects of the amount of Al2O3 and C on the removal efficiency of the composite membranes were deeply examined. At the end of the study, it was determined that the presence of Al2O3 and C enhanced the removal tendency of the cellulose-supported alginate membranes, and the maximum tartrazine removal efficiency as a recovery percentage (R%) was found to be 91.9% at a pH of 3.5 for the Alg-CS/Al2O3 membranes containing 7 g of Al2O3, and 87% at a pH of 1.5 for the Alg-CS/C membranes containing 0.5 g of C.
