Abstract

Crystal growth inhibition and aggregation (coagulation) of calcium oxalate monohydrate crystallites are phenomena of interest in the physical chemistry of stone formation. These phenomena are affected by the presence of adsorbed species at the solid-aqueous phase interface. Inhibitors function by adsorbing at the growing interface. Aggregation tendencies depend on the forces of interaction between particles which are modified by the adsorption of ionic species. Because of the importance of interfacial processes, a study was carried out with calcium oxalate in aqueous suspensions to define better the role of various ionic species in solution. The electrophoretic mobility was used as a measure of the electric potential (zeta potential) near the particle surface. Variations in zeta potential were determined as a function of calcium/oxalate ion activities, pH, and the activities of multivalent ions which are known to function as crystal growth inhibitors.
