Measurement of volatile acid concentration in anaerobic processes by least squares regression of overdetermined titration data
A numerical procedure is presented which determines the volatile acid content of a sample using standard acid titration data. The procedure uses all available titration data instead of the customary single endpoint titration volume. In many cases volatile acid content can be resolved into acetic and propionic acid components. The procedure is verified using solutions of known concentrations. The procedure gives comparable results to the silicic acid chromatography separation technique.
