Small angle scattering measurements showed that the residual cellulose microfibrils increased in diameter from 75.0 ± 2.3 to 110.0 ± 4.2 Å (1 Å = 0.1 nm) after successive treatments with ammonium oxalate – oxalic acid and potassium hydroxide.
Les mesures effectuées sous de petits angles montrent que les microfibrilles de cellulose augmentent en diamètre, passant de 75,0 ± 2,3 à 110,0 ± 4,2 Å (1 Å = 0,1 nm), après des traitements successifs avec l'oxalate d'ammonium – acide oxalique l'hydroxyde de potassium.
