摘要

我们获得了不同羧基含量的细菌纤维素样品。测定了这些样品的交换容量和溶胀程度。开发了一种分光光度法定量测定 CeO2 纳米粒子的程序。研究了 CeO2 纳米粒子在氧化细菌纤维素上的固定化。建立了一个描述纳米颗粒从基质中释放的半经验动力学模型。

Quantitative Spectrophotometric Determination of Cerium Dioxide Nanoparticles in Oxidized Bacterial Cellulose

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.
