Paper Abstract

A study of the light absorption behaviour of kraft pulp suspensions has been carried out. The purpose of the study was to determine whether the measurement of the ultra-violet light absorption coefficient could be exploited as a basis for the development of an on-line lignin content sensor. In order to obtain this measurement, it was first found necessary to compensate for the effects of the pulp light scattering and consistency variation. A method was developed to provide this compensation; however, it appears that the measurement is also significantly affected by species variation.
