Description
Summary:In this paper, ceramic/polymer composite membranes have been prepared to evaluate the efficiency of polymer deposition on the ceramic support from to separation process of Ultrafiltration. Polymers used were polyamide 66 (PA 66) and polysulfone (PSf). The composite membranes were obtained immersing the supports into polymeric solutions to top layer formation. The presence of polymeric layer was observed on the surface of composite membranes by means of the Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). Egg albumin (EA) solution was used to determine the rejection of the composite membranes. The ceramic support showed a higher flux value as expected, since its function is to favor flux passage. The composite membrane ceramic/PA 66 showed a higher flux than that of composite membrane ceramic/PSf. The EA rejection measured by reading the absorbance was 14, 42, and 62% to the support, composite membranes ceramic/PSf and ceramic/PA 66, respectively.
