Determination of dissociable acid groups of organic compounds extracted from soils, using automated potentiometric titration
Because of the physico-chemical properties of soil organic substances (heterogeneity of the functional groups, polymeric nature, precipitation in acidic medium for humic acids) an adequate methodology must be employed to titrate their acidities.
