A method of processing rice waste (husk, straw) into activated carbon is proposed in the study. The thermolysis of the raw material and the activation of the carbonizate were carried out at 500°C and 800°C, respectively. The properties of the obtained activated carbon were determined by standard methods. The porous structure of the activated carbon was studied using scanning electron microscopy. According to the results of the experimental studies, activated charcoal obtained from rice husk corresponds to the WAC brand, whereas activated charcoal obtained from rice straw corresponds to BAU-A grade. This research proposes a rational method of using agricultural waste to obtain useful secondary adsorbent products for adsorption in liquid media.
