Doctoral Dissertation: Application of capillary electrophoretic methods for determining carbohydrates and aliphatic carboxylic acids formed during wood processing
19.11.2012
The doctoral dissertation of Stella Rovio, Licentiate of Philosophy, was examined at Lappeenranta University of Technology 14th November.
Rovio's dissertation is entitled "Application of capillary electrophoretic methods for determining carbohydrates and aliphatic carboxylic acids formed during wood processing".Knowledge of the behaviour of cellulose, hemicelluloses, and lignin during wood and pulp processing is essential for understanding and controlling the processes.
Determination of monosaccharide composition gives information about the structural polysaccharide composition of wood material and helps when determining the quality of fibrous products. In addition, monitoring of the acidic degradation products gives information of the extent of degradation of lignin and polysaccharides.
This work describes two capillary electrophoretic methods developed for the analysis of monosaccharides and for the determination of aliphatic carboxylic acids from alkaline oxidation solutions of lignin and wood.
Associate professor, Ph.D Vesa Virtanen, University of Oulu, acted as the opponent. Professor Heli Sirén of Lappeenranta University of Technology acted as custos.
