Question

name the semipermeable membrane used in reverse osmosis​

Answer 1

Answer:

Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semipermeable membrane. The semipermeable membrane allows the passage of water, but not ions (e.g., Na+, Ca2+, Cl-) or larger molecules (e.g., glucose, urea, bacteria).

Answer 2

Answer:

The diffusion of water through a selectively permeable membrane is called osmosis. ... In the process of reverse osmosis, thin film composite membranes (TFC or TFM) are used. These are semipermeable membranes manufactured principally for use in water purification or desalination systems.
