Abstract：

A novel Ag@MoS2-GO composite nanofiltration membrane was prepared by Vacuum filtration using PES microfiltration membrane with an average pore size of 100 nm as carrier and modified by dopamine.The optimal mass ratio of MoS2 and GO was obtained by adjusting MoS2 load.AgNP was further grown on MoS2 nanosheet and intercalated on GO nanofiltration layers to achieve the regulation of Ag@MoS2-GO nanofiltration membrane performance.The results showed that MoS2-GO membrane had the best nanofiltration performance when the mass ratio of MoS2 to GO was 6∶1.The rejection rate of four typical dyes was above 95%,and the water permeability was about 1.13 L/(m2·h·bar),which was nearly two times higher than that of pure GO membrane.While maintaining the same excellent dye retention performance as MoS2-GO membrane,Ag@MoS2-GO membrane has a water permeability of 1.89 L/(m2·h·bar), which is 0.7 times higher than MoS2-GO membrane.The rejection rate of Ag@MoS2-GO membrane to four salts satisfies the following relation:R(Na2SO4)>R(MgSO4)>R(NaCl)>R(MgCl2).and the rejection rates were 78%, 67%, 51% and 41%,respectively,which were significantly higher than MoS2-GO nanofiltration membrane,and the membrane showed good stability.
