IMMOBILIZATION AND STABILIZATION OF TiO 2 NANOPARTICLES IN ALKALINE- SOLIDIFICATED CHITOSAN SPHERES WITHOUT CROSS-LINKING AGENT

摘要: TiO2 nanoparticles have been shown to wide applications in multiple fields. The combining of polymer and form films or hydrogel materials has further advantages such as reusable, non-aggregated, recyclable good dispersible. Although the chitosan particles can be easily obtained by crosslinking method, cytotoxicity some commonly used agents made it limited biological applications. In this article, a facile approach synthesis nanoparticles- composite spheres without was presented. proposed stabilize disperse matrix, an alkaline solidification process. diameter synthesized is ranging from 1.5 mm 2.5 mm. With UV-Visible spectroscopy, EDS, XRD FTIR, were embedded spheres. fabricated are potential for multi-filed applications, bactericide, wastewater pollutant treatment, others.
