“…In addition, the O 1s peaks at 531.75eV and 532eV could be due to the presence of (C-O) and (AL-O) bond states in the samples. The peak area is proportional to the number of atoms of the element studied (Asli, Mokhtar, et al, 2022), and by calculating the respective share of each area, we obtain the atomic composition of the sample. We can see that the percentage of oxygen is 75% and carbon 25%.…”

This study focuses on developing ceramic ultrafiltration membranes using locally sourced kaolin clay and feldspar. An active layer composed of graphene and alkoxide is added to enhance the performance of these clay supports. This layer is thin, porous, and can vary in thickness. The support and filter layer's porous properties are characterized using SEM, DRX, ATG/ATD, XPS, and FTIR techniques. Filtration tests are conducted on modified porous tubular supports using cationic and anionic dye solutions. The filtration is performed tangentially at a pressure of 3.5 bar and a processing time of 120 minutes. The retention rates of the colored solutions are measured using a UV-visible spectrophotometer. The results show a 100% retention rate for supranol yellow and orange II at a concentration of 10-4 M, while for crystal violet and malachite green, the retention rates are 92.03% and 95.30%, respectively.
