摘要：
Samples of bacterial cellulose with different contents of carboxyl groups have been obtained. The exchange capacity and degree of swelling of these samples were determined. A procedure was developed for the quantitative spectrophotometric determination of CeO2 nanoparticles. The immobilization of CeO2 nanoparticles on oxidized bacterial cellulose was studied. A semi-empirical kinetic model describing the release of nanoparticles from the matrix was formulated.
