OBTAINING NANOSTRUCTURED CARBON CERAMIC SORBENTS AND STUDYING CHARACTERISTICS
Keywords:
sorbents, rice husks, fitolity, activation, silicon dioxideAbstract
Carbon nanostructured sorbents are investigated in this paper. Sorbents obtained from Rice husks by means of vapor-gas / chemical activation, since It is a unique material in terms of the minimum content of toxic substances, as well as the presence of phytolites in the form of nanosized silicon dioxide, serving as a template for creating an additional volume of required meso / macropores in the nanoscale range, which will promote the adsorption of medium molecular nitrogen toxins, and carbon-ceramic Sorbents from the carbonized rice husk (CRH) and clay by activation of phosphoric acid at a temperature of 900-1200 °C. The basic physicochemical and structural characteristics of the samples obtained were studied.
