Abstract

The article presents the results of studying the properties of adsorbents obtained from rice husk. To increase the sorption capacity, the raw material was subjected to heat treatment under various conditions and at different temperatures, and then was used to bleach cotton oils. The amount of added sorbent was from 1 to 4%. According to the results of laboratory tests, adsorbents that have undergone thermal activation at a temperature of 800°С have the highest porosity and bleaching ability. 800°С.
