The oxygen (1s) ESCA peak for aspen explosion pulp consists of two components, O1 and O2. A tentative assignment was made for them. O1 with lower binding energy is assigned to oxygen in lignin; while O2 comes mainly from the oxygen elements in carbohydrates. Thus, an O1 area percentage might be viewed as a measure of lignin exposed on the fiber surface. Sulfur (2p) spectra show that the sulfur on the fiber surface of the pulps studied here is in the form of sulfonate groups. Compared to… CONTINUE READING
