Nitrogen sorption as a tool for the characterisation of polysaccharide aerogels [PDF]

open access: yes, 2011
Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, k- carrageenan, and agar) have been characterised by physisorption ofN2. Surface areas as high as 570m2 g−1 have been measured.
