Abstract: |
Hydrogen bonds may form between polar organic molecules and polyamides on the surface of the nanofiltration membrane.This course is accompanied by electronic transport phenomena. As a result, electrostatic effect and charge density on the nanofiltration membrane surface get lower.And this causes rejection rates changed. The values of surface charge density with different concentration p-nitrophenol were measured to investigate the relationship between hydrogen bond and rejection. The results show that with the increase of concentration of p-nitrophenol surface charge density of the nanofiltration membrane reduced gradually and rejection got lower. |
