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.
