A novel method for the determination of carbonyl groups in cellulosics by fluorescence labeling. 2. Validation and applications.


Fluorescence labeling with the marker carbazole-9-carboxylic acid [2-(2-aminooxyethoxy)ethoxy]amide was shown to be a promising approach toward the accurate determination of carbonyls in cellulosic materials. Combined with gel permeation chromatography in DMAc/LiCl with fluorescence/multiple-angle laser light scattering/refractive index detection, the… (More)
