Which of these should be a characteristic of the semi permeable membrane used in ultra filtration method?
- A. The membrane should be a polymer material
- B. The pore size of the membrane should be very small
- C. Both A and B
- D. None of the above
Step-by-step solution
Ultrafiltration relies on a semipermeable membrane with very small pores to separate particles based on size. While polymer membranes are commonly used, they are not strictly required; other materials like ceramics can also be used. Therefore, the essential characteristic is small pore size, not necessarily a polymer material.
