NIRDRS Determination of Moisture in Pulp of Cellulose Acetate in Acetone

Near infrared diffuse reflectance spectroscopy (NIRDRS) was applied to the non-destructive determination of moisture in pulp of cellulose acetate in acetone,and the best mathematical model was established and given in this paper.Various influential factors to the prediction ability of the modified partial least square method,including different regression methods,spectral range,and the number of principle components,were discussed.
