Acetone and
hot-water extracted C&D wood waste were used for Klason lignin
determination and carbohydrate compositional analysis. The
Klason lignin content was analyzed by the NREL procedure but
the carbohydrate composition was analyzed by acid hydrolysis followed
by 1H-NMR spectroscopy (NREL, 2008; Shin and Cho, 2008).
Acidic filtrates were analyzed by Bruker Avance NMR Spectrometer
(600 MHz for proton).
