PZSE: Analytical-computational approach to its determination from potentiometric titration data

M. E. Alves, C. R. Macedonio, A. Lavorenti

01/Jun/2002

The point of zero salt effect (PZSE) of soil samples is usually determined by a graphic method where the PZSE corresponds to the pH value observed at the crossing point of drafted potentiometric titration curves. Although the use of graphic software decreases the personal bias that normally occurs when the titration curves are drafted by hand, this determination method can be time-consuming when there is a great number of soil samples. The present work aimed to develop a software to […]
