Abstract
Indonesia is one of the countries with the highest levels of air pollution in the world. Air pollution in Indonesia, especially in Jakarta due to the number of private vehicles increased at least 10% every year. This air pollution can have an impact on public health. One effort to do as a protection of people health is to use a mask. Activated carbon can be coated to mask in order to improve the effectiveness in reducing the pollutants. One good material used as material for activated carbon is coconut shell. Selection of coconut shell as the raw material of activated carbon is also based on cellulose content of 26.06%, hemicellulose content 27.07% and a lignin content of 29.40% in the dry state. This research was done in some variation such as activation methods, activated carbon mass, and adhesive material types. Based on pollutants adsorption test, mask with 6 grams of activated carbon, chemically activated, and used TEOS as adhesive is the best variation that able to adsorb as much 76,25% of CO2 Pollutants. Mask made in this research, has saturation time as long as 4 hours under high CO2 concentration.
Highlights
The use of motor vehicles have an impact on public health as motor vehicles emit harmful substances such as lead / pb, suspended particulate matter (SPM), nitrogen oxide (NOx), hydrocarbons (HC), carbon monoxide (CO), carbon Dioxide (CO2) and sulfur oxide (SOx)
Coating coconut shell activated carbon with dip coating method on a mask is a new way to decreasing the concentration of various air pollutants, especially CO2 which has the highest concentration among other harmful emission gas
These results show that TEOS is more suitable to applied as an adhesive in activated carbon coating process than Sodium Silicate
Summary
The use of motor vehicles have an impact on public health as motor vehicles emit harmful substances such as lead / pb, suspended particulate matter (SPM), nitrogen oxide (NOx), hydrocarbons (HC), carbon monoxide (CO), carbon Dioxide (CO2) and sulfur oxide (SOx). Among of these hazardous substances, carbon dioxide gas (CO2) has the greatest composition on motor vehicle emissions of 14% [5]. Coating coconut shell activated carbon with dip coating method on a mask is a new way to decreasing the concentration of various air pollutants, especially CO2 which has the highest concentration among other harmful emission gas
