| titleOfInvention | A kind of graphene oxide composite nanofiltration membrane and preparation method thereof |
| abstract | The invention provides a graphene oxide composite nanofiltration membrane and a preparation method thereof. The method comprises the following steps: drop the graphene oxide dispersion prepared by the improved Hummers method on one side of the base membrane, uniformly coat it with a coating rod, and dry it. , and partially reduced to obtain a graphene oxide composite nanofiltration membrane. The method avoids the harsh requirements on conditions of the traditional nanofiltration membrane preparation process, and overcomes the disadvantage that the existing graphene oxide composite nanofiltration membrane preparation method is difficult to produce continuously and in a large area. The cost is low and pollution-free, so it is of great significance for the industrial application of graphene oxide composite nanofiltration membranes. The graphene oxide composite nanofiltration membrane prepared by this method has a water flux of 3.7-13.0kg/(m 2 ·h·bar) when the operating pressure is 3.0-5.0 bar and the concentration of Na 2 SO 4 solution is 1.5g/L. , the salt cut rate is 39.1 to 91.8%. |
