Abstract

A systematic study of factors affecting the parameters of the electrophoretic separation of synthetic nanocrystals of calcium hydroxyapatite is performed. Data of capillary zone electrophoresis and scanning electron microscopy are compared. Optimal conditions for the determination of calcium hydroxyapatite by capillary zone electrophoresis are selected. It is shown that calcium hydroxyapatite nanoparticles are polydisperse; the nanostructures exist in a variety of clusters and floccules with characteristic sizes, which is confirmed by the coinciding data of capillary zone electrophoresis and scanning electron microscopy. A linear dependence of the normalized total area of calcium hydroxyapatite nanoparticles on their concentration in suspension is obtained.
