摘要：NOVELTY - The production of a polymer and hollow fiber combined nano-filter membrane includes immersing a basic membrane in a water-phase solution, immersing in an oil-phase solution, reaction, drying in air, repeating the steps, and heat treating at 50-90degreesC for 0.5-5 hours. The membrane intercepts sodium sulfate by more than 90% and sodium chloride by less than 3.5%.
