The Influence of Filler in Composite Cellulose Acetate Membranes for Proteins Recovery

Article Preview

Abstract:

The present work study the influence of filler in proteins recovery using cellulose acetate membranes. There were studied carbon nanotubes and graphene oxide as synthetic fillers and bone powder and inulin as natural fillers. The used proteins for work were Bovine Serum Albumin and hemoglobin. The best retention results were shown by the composite membranes with carbon nanowalls, fact that can be explained by the chemical interactions between carbon nanotubes surface and proteins molecules. Synthesized membranes were characterized by Scanning Electron Microscopy and Fourrier Transformed infrared Spectroscopy and the proteins retention was determined by UV-Vis Spectroscopy.
