Quantitative Spectrophotometric Determination of Cerium Dioxide Nanoparticles in Oxidized Bacterial Cellulose
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.
