Composite semipermeable membrane and process for production thereof |
| abstract |
Disclosed is a composite semipermeable membrane comprising a microporous support membrane and a separation function layer arranged on the microporous support membrane, wherein the separation function layer comprises a condensation product produced by the condensation of at least one ion selected from the group consisting of ions of trialkoxysilanes each having an imidazolium group and a conjugated base of a polymer having at least one acidic group. The composite semipermeable membrane has excellent selective separation performance for univalent ions over bivalent ions. Also disclosed is a process for producing the composite semipermeable membrane. The composite semipermeable membrane can be used suitably in the various water treatment fields such as the desalination of sea water and the production of drinkable water. |
