SPECIFICS OF MECHANICAL TREATMENT OF RICE HUSK FOR CARRYING OUT SOLID-PHASE INTERACTION OF SILICA WITH POLYPHENOLS
Abstract
Rice husk is characterized by high-strength characteristics and chemical stability, has a low-nutritional value, a low bulk density, and a high ash content.The goal of the present work is the development of a treatment method method for obtaining compositions based on polyphenols from the plant raw material and biogenic silicon dioxide from rice husk. Efficiencies of mills with different types of grinding were compared. The most effective grinders for the high-quality treatment of rice husk are roller and attrition mills. The mechanical treatment causes an increase in the specific surface, a decrease in particle size, structural disordering with the amorphization, separation into different kinds of tissues and formation of active sites on silica. In the case when rice husk is used as the source of silicon dioxide for interaction with polyphenols, it is preferred to use the initial plant raw material, silanol group-containing. The interaction of silanol group of rice husk silica with polyphenols result in the formation of surface complexes.
