| description | The invention discloses a preparation method and application of a CuO@CuS/PVDF water treatment composite membrane. The preparation method comprises the following steps: (1) calcining precipitates generated by reaction of a Na2CO3 solution and a CuSO4 solution by adopting a chemical coprecipitation method to obtain nano CuO powder; (2) adding nano CuO powder into a CuSO4 solution, uniformly stirring, adding a Na2S2O3 solution into the mixed solution, stirring to obtain fluorescent green precipitates, transferring the fluorescent green precipitates into a microwave reactor, and preparing CuO@CuSnano composite powder by adopting a microwave method; (3) adding PVDF particles into a DMAC solvent, carrying out a reaction in a water bath with a constant temperature of 80 DEG C so as to form a homogenous solution; adding (NaPO3)6, PVP and CuO@CuS nano composite powder at the room temperature, uniformly stirring, standing to eliminate foams, pouring the solution on a flat glass plate, uniformly scraping, and finally s |
