Abstract :The pervaporation is a promising process to achieve highly efficient desalination performance. In this study, Hydroxypropyl methylcellulose insert ignore into journalissuearticles values(HPMC); and Polyvinylpyrrolidone insert ignore into journalissuearticles values(PVP); polymers were chosen in the synthesis of blend membranes and used for pervaporative desalination process. The chemical structure and thermal stability of membranes were analyzed by using Fourier-transform infrared spectroscopy insert ignore into journalissuearticles values(FTIR); and Thermogravimetric analysis insert ignore into journalissuearticles values(TGA);, respectively. The effects of PVP ratio in membrane and operation temperature on the flux and salt rejection were examined. The highest separation efficiency was acquired as water flux of 4.86 kg/m2h and a salt rejection of 99.9% using 50 wt% PVP ratio at 40 °C. The obtained results show that HPMC/PVP blend membrane has a great potential for water desalination via pervaporation.
