Effective application of dendrimers in the field of ultra-low pressure reverse osmosis membrane.

Dendrimer-based ultra-low pressure reverse osmosis membrane can effectively retain a variety of salts, such as sodium sulfate, sodium chloride, magnesium sulfate, retention rate reaches 92%, in particular sodium sulphate, up to 98%. The membrane has high flux, and low operating pressure. Water flux can reach 30-40 L • M-2 • h – 1, operating pressure was 0.6MPa. The film has good resistance to chlorine, acid and alkali resistance is little weaker. In addition, the membrane has excellent separation performance for PEG-200, showing its promising application in separation small organic molecules from the water.
