| Abstract: | The pH -sensitive membrane can respond to the change of pH to cause the change of net charge on membrane and the structural transition of membrane pore or graft chains, and then to affect separation behavior. The types and preparation of pH - sensitive membrane are introduced. The stream potential could characterize the charge distribution on the surface of pH - sensitive membrane. The research on application of pH - sensitive membrane to selective separation and drug- release technology is also reviewed. |
