摘要: Abstract Chemical changes in the dissolved high-molecular-mass material from silver birch (Betula pendula) kraft pulp during oxygen–alkali delignification stage (O) and subsequent totally chlorine-free (TCF) bleaching sequence (X–Z–EOP–AZ–EP–S) were investigated by analytical pyrolysis (pyrolysis–gas chromatography/mass-sensitive detector (Py–GC/MSD)). In addition, data subjected to chemometric analysis, resulting a rapid method for determining with reasonable accuracy, example, mass proportion of carbohydrates lignin effluents each treatment stages. The was calibrated chemical analysis on same effluents.
