Rapid semi-quantitative determination of aspen lignin in lignocellulosic products; pp. 105–112 [PDF]
Proceedings of the Estonian Academy of Sciences, 2015 In the present study different methods for the determination of aspen lignin were investigated. In experiments, dried samples of extractive-free aspen wood and grinded bleached-chemo-thermo-mechanical-pulp (BCTMP) of aspen were used. For isolating lignin
