Activated Carbon Adsorption Effectiveness in Coconut Shell Lowers Carbon Monoxide Indoor Air

Abstract

The concentration of air pollutants in the home is greater than the outside and most of the pollutants come from the combustion gas containing carbon monoxide (CO) that are harmful to human health, it is necessary innovation air control to reduce levels of CO gas by using coconut shell charcoal. The aim to determine the effectiveness of coconut shell activated carbon adsorption in carbon monoxide gas reduction in indoor air. The research method using one group pre-post test design and analysis of data using paired t test. The results showed that decreased levels of CO gas after recovery tool room air through the use of coconut shell charcoal with a suction flow of 2.2 l/min at 185.3 ppm and percentage decline 73.9%. The results showed that there was a significant difference in reduction in carbon monoxide gas.
