In this study, the effect of evaporation time of tetrahydrofuran solvent on the properties and performance of polymeric membranes based on a mixture of two polymers, polyvinyl chloride and polymethyl methacrylate was investigated. For this purpose, after preparing a polymeric solution from the mentioned polymers, in the phase inversion process, the membranes were made using immersion method in non-solvent bath at evaporation times of 0, 15, 30 and 45 seconds. To investigate the effect of evaporation time on the properties of the prepared membranes, variables of water content, porosity, pore size, flux and membrane rejection were tested.
