titleOfInvention | A kind of preparation method of reverse osmosis composite membrane modified by graphene oxide quantum dots-silver phosphate composite material |
abstract | The invention relates to a preparation method of a reverse osmosis composite membrane modified by graphene oxide quantum dots-silver phosphate composite material. In the method, the composite material is dispersed in an aqueous phase solution of polyamine, and the polybasic acid chloride is dissolved in an organic solvent An oil phase solution is prepared, a polysulfone membrane is used as a base membrane, an interfacial polymerization method is used, and a reverse osmosis composite membrane modified by a graphene oxide quantum dot-silver phosphate composite material is prepared by simple and efficient electrostatic driving. The reverse osmosis composite membrane has high water flux and maintains a good level of salt interception, breaking the limit of the "upper limit balance", and at the same time showing excellent bactericidal performance, and has a wide range of applications in the fields of seawater desalination, brackish water treatment and membrane separation. application prospects. |
