Abstract

FT-Raman spectroscopy is used for rapid quantification of hardwood pulp lignin. The ratio of the integrated area of the lignin band near 1600 cm^-1 to that of cellulose in the region of 1200-1010 cm^-1 behaves linearly with measured κ number for two separate sets of kraft hardwood pulp samples. Spectra and quantitative results of the hardwood samples, both with and without base line correction, are compared. Sources of error and measurement reproducibility are discussed. The method described shows potential for at-line process analysis of wood pulp.
