| Abstract: |
| In this research, Cu2O nanoparticles were synthesized firstly by electrochemical method, and synthesized nanoparticles were applied to modification of the nanofiltration membranes. Different concentration of nanoparticles as an additive was incorporated in the PES as membrane matrix for preparation of PES/Cu2O nanofiltration membranes. Prepared membranes and synthesized nanoparticles were analyzed by Fourier transform infrared (FT-IR), Scanning electron microscopy (SEM). The FTIR analysis showed the formation of desirable bonds in the synthesized nanoparticles. The SEM image of nanoparticles showed good distribution of particle size in the nano-scale. The separation performance of the fabricated membranes was investigated by the pure water flux and Na2SO4 rejection. The results showed the highest pure water flux of 36.78 L/m2h for M1 in 0.05 wt.% of Cu2O nanoparticles. Moreover, Na2SO4 rejection enhanced to 66.94% in 2wt.% of Cu2O nanoparticles for M5 and it was 29.46% in 0.05 wt.% of Cu2O nanoparticles for M1 membrane. Furthermore, the modified membranes showed good antifouling properties. |
