Abstract: Multi-walled carbon nanotubes (MWCNTs) loaded with ferric oxide (Fe3O4) (MWCNTs/Fe3O4) were prepared by mixed acid modification with concentrated sulfuric acid (H2SO4) and concentrated nitric acid (HNO3) at a mass ratio of 3∶1,ultrasonic mixing and chemical hydrothermal method.The MWCNTs/Fe3O4/PVDF blend membranes were prepared by blending the acidified MWCNTs/Fe3O4 with polyvinylidene fluoride (PVDF),polyethylene glycol (PEG),N,N-dimethylacetamide (DMAC).The membrane surface,contact angle,pure water flux,porosity,average pore diameter and retention rates of 5 substances such as drugs and personal care products (PPCPs) and sodium alginate were tested.The results shown that the contact angle of MWCNTs/Fe3O4/PVDF was 56.65 degrees,the pure water flux of 152.866L·m2/h,the retention rates of humic acid (HA),sodium alginate (SA),bisphenol A (BPA) and bovine serum albumin (BSA) were 59.71%,71.16%,59.10%,76.00%,respectively.The propertis of film were improved than pure PVDF film.The addition of MWCNTs/Fe3O4 improved the overall performance of PVDF film.
