NMR studies of lignin models, derivatives and bleaching effluents
NMR problems related to assignment techniques and relaxation restrict the use of NMR in the structural analysis of lignin. These problems have been addressed in three practical studies in this thesis involving a lignin ...
Structure and mobility of lignin in relation to pulp washing and bleaching
The roles of molecular size and structure were investigated in relation to the extent of peroxide bleaching and lignin adsorption on pulp. Structural analysis of components from effluents generated by peroxide bleaching ...
