metadata.value: Novel mixed matrix dense and supported membranes based on biopolymer sodium alginate
  (SA) modified by fullerenol were developed. Two kinds of SA–fullerenol membranes were investigated:
  untreated and cross-linked by immersing the dry membranes in 1.25 wt % calcium chloride (CaCl2)
  in water for 10 min. The structural and physicochemical characteristics features of the SA–fullerenol
  compositewere investigated by Fourier-transforminfrared (FTIR) and nuclearmagnetic resonance (NMR)
  spectroscopicmethods, scanning electron (SEM) and atomic force (AFM)microscopies, thermogravimetric
  analysis (TGA), and swelling experiments. Transport properties were evaluated in pervaporation
  dehydration of isopropanol in a wide concentration range. It was found that the developed supported
  cross-linked SA-5/PANCaCl2 membrane (modified by 5 wt % fullerenol) possessed the best transport
  properties (the highest permeation fluxes 0.64–2.9 kg/(m2 h) and separation factors 26–73,326) for the
  pervaporation separation of the water–isopropanol mixture in the wide concentration range (12–90 wt %
  water) at 22C and is suitable for the promising application in industry.
