摘要：Method for enabling the paper pulp production process to be controlled insuch a way that the hexenuronic acid content in the pulp can be minimized and the color
reversion of the pulp and/or the pulp products thereby minimized. The method is basedon measurements of the optical properties of a fiber containing substance or processstream in the wavelength region 232±5 nm and another wavelength interval. A significantvalue for the current hexenuronic acid content is formed by correcting the intensity in thespectrum around 232 nm by the corresponding optical quantity at the other wavelengthinterval. The content of the hexenuronic acid content that is determined by the analysis isthen used for controlling conditions in the process stage.
