In this work, hybrid carbon-polymeric membranes were synthesized by an immersion-precipitation method using polysulfone (PSf) as the membrane matrix, methylcellulose (MC) as pore forming agent and commercial powdered activated carbon (PAC) as inorganic adsorbent additive. All the components were dissolved in N-methylpyrrolidone (NMP) to prepare the casting solutions. The surface hydrophilicity of the prepared membranes was determined by measuring water contact angle. The effect of methycellulose and activated carbon on the morphology of the membranes was examined by scanning electron microscopy. Hybrid membranes performances were tested in terms of water permeability and rejection of selected pharmaceuticals at a concentration of 10 ppm. Results showed that the hydrophilicity of the hybrid membranes was improved by methylcellulose and activated carbon component. The asymmetric structure of the prepared membranes was more porous by adding activated carbon. The water permeability of the hybrid membranes was better than non-hybrid ones. A high rejection rate was obtained with hybrid carbon-polymeric membranes compared with membranes without carbon.
