<div class="section abstract"><div class="htmlview paragraph">This research effort is to optimize the conditions to minimize carbon monoxide
(CO) gas emissions utilizing activated carbon derived from rice husks, an
abundant agricultural waste. In the automobile industry, addressing vehicular
emissions is crucial due to environmental ramifications and stringent regulatory
mandates. This study presents an innovative and potentially cost-effective
solution to capture CO emissions, mainly from motorcycles. The eco-friendly
nature of using rice husks and the detailed findings on optimal conditions (20
m/s gas flow rate, 0.47 M citric acid concentration, and 30 g mass of activated
carbon) make this research invaluable. These conditions achieved a commendable
CO adsorption rate of 54.96 ppm over 1250 s. Essentially, the insights from this
research could spearhead the development of sustainable automobile exhaust
systems. By integrating activated carbon into these systems, there’s potential
to capture CO and possibly other detrimental gases, reducing the environmental
impact of vehicles. This approach might herald a new era in environmentally
conscious automotive technologies.</div></div>
