Paper Abstract

We are working toward the development of an instrument for the continuous on-line measurement of the lignin concentration in wood pulp. The system will be used as a primary sensor for process control in the pulp and paper industry. The measurement is based on the fluorescence properties of lignin. The instrument will use an optical fiber probe to separate the light generation, detection, and analysis equipment from the hostile process environment. To provide the background data necessary for the design of the instrument, we have characterized the fluorescence properties of lignin bound to wood pulp. A nitrogen laser was used as the excitation source and an intensified photodetector array capable of fast grating was used to obtain time-resolved fluorescence spectra.
