<p>A method for controlling the addition (33) of cationic additive materials (28) to a paper mill slurry (22) used to neutralize the anionic contaminants in a papermaking process which utilizes total organic carbon measurements (32, 34) of samples of the slurry as an indicator of the cationic demand of the paper mill slurry. The method of the present invention discloses the discovery that measurements of the total organic carbon (32, 34) taken form filtered samples of the papermaking slurry correlate very well to cationic demand measurements of the papermaking slurry (22). Therefore, measurements of the total dissolved organic carbon content may be used to determine the desired addition rate of cationic additives (28) in a very convenient and reliable manner.</p> |
