| titleOfInvention | An acid-resistant high-flux polyarylene ether composite nanofiltration membrane, preparation method and application |
| abstract | The invention discloses a preparation method of an acid-resistant high-flux polyarylene ether composite nanofiltration membrane. A non-planar conformation compound containing at least two hydroxyl groups is used as a raw material to prepare an aqueous phase solution, and a three-phase solution containing at least two carbon-chlorine bonds is used as a raw material. The azine compound is used as the raw material to prepare the oil phase solution, and the water phase solution and the oil phase solution are formed by interfacial polymerization on the porous support membrane to obtain an acid-resistant high-flux polyarylene ether composite nanofiltration membrane. The prepared acid-resistant high-flux polyarylene ether composite nanofiltration membrane has a porous support membrane layer and a polyarylene ether separation layer, and the polyarylene ether separation layer has a unique water permeation microporous channel, and the polyarylene ether composite nanofiltration The water permeability of the membrane is greatly improved, the water flux is as high as 20L m ‑2 h ‑1 bar ‑1 , the dye rejection rate reaches 99%, and the polyarylene ether composite nanofiltration membrane also has excellent acid resistance. The preparation method of the invention is simple, the equipment requirement is low, the water treatment cost can be effectively reduced, and the invention is suitable for industrial fields such as acid waste water treatment. |
