Problem formulating. To increase the sorption capacity of calcium carbonate microparticles used as core for the development of targeted drug delivery, EDTA chelation of calcium ions was used to form a developed active surface of the particles. Goal. Is in modification of the surface of micron and submicron calcium carbonate vaterite particles using EDTA chelation of calcium ions and studying the effect of particle processing on their sorption capacity.

Result. It was shown using scanning electron microscopy that EDTA treatment of the CaCO3 surface leads to an increase on the surface roughness of the particles, as well as an increase on their sorption capacity according to spectrophotometric data. Practical meaning. Use of adsorption to encapsulate the active substance inside the carriers. It is shown that an increase in the sorption capacity of particles leads to an increase in the amount of a substance inside its volume.
