Preparation of Biosilica-enriched Filler and an Example of its Use in a Papermaking Retention System, 2006 International Conference on Nanotechnology

PressWeb.jpg

Silica deposited within the plant tissue in small bodies –phytoliths is leached by an alkaline solution. Up to 70-75% of biosilica from wheat/rice straw becomes solubilized. The reaction kinetics is shown. Solubilized biosilica is recovered and reused in the papermaking process, via the causticizing reaction. The chemical composition, and surface properties (surface charge) of newly designed filler is shown. The positive effect of this filler in nano-particle retention system is demonstrated.
