The study proposes a process for converting rice residue (straw, husk) into activated carbon (AC). The raw material has been thermolyzed at 500ºС, and the carbonizate was activated at 800ºС. Appropriate techniques were used to study the characteristics of the AC produced. SEM has been used to examine the porous structure of activated carbon. Activated charcoal made from rice husk belongs to the wood activated carbon (WAC) product, while activated carbon derived from rice straw compares to the BAU-A grade, according to the results of the experiments. This study presents a sensible strategy for obtaining viable secondary adsorbent materials for adsorption in liquid media from agricultural by - products.
