عنوان انگلیسی The Effect of Silica Nanoparticles’Coating on the Ion Resolution of Anionic Membrane in SGP System
چکیده انگلیسی مقاله One of the new sources of renewable energy, is salinity gradient power (SGP) being described as; the entropy energy of mixing the two solutions with different salt concentrations. The extraction of this energy is possible through SGP; the function of this system is based on membrane processes. A system of reverse electrodialysis (RED) was used in this study. Power density (W/m2) and energy efficiency of the system were evaluated due to the impact of nanotechnology on the use of membranes. The analyses showed that when the concentration of silica nanoparticles in the matrix membrane used in the system is 20 percent and when ion concentration in the solution is 0.055mol/lit, the selectivity of the membrane for ions will be Na+, 98.4 percent. However, the selectivity of matrix membrane without the presence of nanoparticles is 82 percent. Also compared to non-nanoscale membranes, the efficiency is increased about 11 percent due to the use of the particles on the anionic membrane as well as their appropriate structure design.
