The oxygen (1 s) ESCA peak for aspen explosion pulp consists of two components, O1 and 02. A tentative assignment was made for them. Ol with lower binding energy is assigned to oxygen in lignin; while 02 comes mainly from the oxygen elements in carbohydrates. Thus, an O1 area percentage might be vie

The surface composition of explosion pulp and conventional CMP and CTMP underwent ESCA spectroscopy. Explosion pulps exhibited a higher oxygen-to-carbon ratio and less C1 peak areas compared to conventional CMP/CTMP. Based on the theoretical O/C ratios and C1 contents for the main components of wood
