摘要：
The influence of sodium oleate and ultrasonic treatment on the stability of aqueous suspensions of calcium hydroxyapatite is studied by capillary zone electrophoresis. Chances for the assessment of the stability and dispersion composition based on the electrophoretic behavior of particles are demonstrated. For stable suspensions a linear relation of the normalized peak square to the concentration of calcium hydroxyapatite is found. The data of capillary zone electrophoresis are verified with the data of scanning electron microscopy and dynamic light scattering.
