Abstract: |
|
The safety of potable water has become one of the major problems. Traditional membrane separation technology cannot simultaneously remove pollutants in water and retain beneficial substances. In order to solve this problem, our research team has been carrying out basic researches and key technology researches of the adsorptive separation membranes, which combined adsorptive functional materials and filtration membranes. Under the forced convective mass transport, the pollutants were rapidly removed from water via the non-covalent interactions with the adsorption groups, while the beneficial substances can be retained in water. From the perspective of the structural design, this paper reviewed the various construction methods (surface gel filling, bulk filling and in-situ composite) of the adsorptive separation membrane with multiple functions, such as selective adsorption, anti-fouling, antibacterial, stimulus response, etc. Further, the separation mechanism and the relationship between the material structure and separation performance were elaborated, providing theoretical and methodological supports for the development of high-performance adsorptive separation membrane. In addition, the research achievements have been transferred from basic research to practical application. Also the developed hollow fiber membrane materials have been applied to household water purification equipment, and large-scale production and promotion have been realized. |
