This document specifies procedures for the laboratory determination of the total elemental sulfur and the sulfate half-ester content of cellulose nanocrystals (CNCs) by inductively coupled plasma-optical emission spectroscopy and conductometric titration, respectively, including sample preparation, measurement methods and data analysis.<\/p>\n
This document is applicable to the characterization of CNCs:<\/p>\n
a) with all monovalent counterions (particularly hydronium and sodium cations);<\/p>\n
b) which are either in the never-dried state in aqueous suspension, or have been redispersed from a dried form; and<\/p>\n
c) which have been extracted from any naturally occurring cellulose source using a range of sulfuric acid hydrolysis conditions, or have been sulfated post-hydrolysis using sulfuric acid.<\/p>\n","protected":false},"excerpt":{"rendered":"
