SYNTHESIS AND CHARACTERIZATION OF ASYMMETRIC ULTRAFILTRATION MEMBRANE MADE WITH RECYCLED POLYSTYRENE FOAM AND DIFFERENT ADDITIVES

摘要: This paper reports the synthesis and characterization of asymmetric ultrafiltration membrane made from recycled polystyrene foam (PS) with different additives polyvinylpyrrolidone (PVP). The is currently employed as packing, in fabrication glasses dishes. inexpensive easy to acquire and, at less Mexico, not a conscience exists recycled. membranes where prepared by phase inversion process casting solution containing polymer, l-methyl-2-pyrrolidone (NMP) solvent, polyethylene glycol (PEG) molecular weights dioctyl phthalate (DOP) additives. characterized terms pure water permeation (PWP), weight cut off (MWCO), flux morphology. results revealed that addition PEG high weights, produce higher permeation. presence affects surface roughness
