RELIABLE DETERMINATION OF STARCH CONCENTRATION IN PAPERMAKING PROCESS WATERS WITH MULTIVARIATE CALIBRATION OF THE TRADITIONAL STARCH-IODINE METHOD

摘要

A multivariate calibration of the well-known iodine starch method was performed. Even at high turbidity the model was able of predicting the starch concentration of filtered pulp samples. The prediction was almost as good for samples filtered with a 200-mesh wire as with filter paper, indicating reliable quantification of both aggregated and dissolved starch.
