Abstract

Activated carbons are black solid substances having an extreme porosity (space) enclosed by carbon atoms. Because of that, they are powerful adsorbents that are used in removal of hazardous contaminants existing in gas or liquid phases. These powerful adsorbents used also among history, are the most common adsorbents in industry. Especially, behind using for removal of hazardous compounds in drinking or waste water, they are used for removal of contaminants in air to increase indoor air quality. Generally, they are used in powder, granulate and fiber/cloth forms. Although their common usage is granulate form, the fiber/cloth form has great attention because of having several advantages over granular activated carbon (GAC) such as even distribution of micropores, higher value of surface area, higher dynamic adsorption capacity and adsorption rate, and smaller critical bed depth. Moreover, activated carbon cloth (ACC) provides ease in applications because of its elasticity and lightness. ACC has exhibited outstanding performance in adsorbing odors, solvents, bacteria, virus and all of the contaminants that exist in air, gas, water and other liquids. In this work, the removal of harmful chemicals in cigarette smoke was studied in dynamic phase using a new product of activated carbon cloth (GDSEL 651) by proposing a new strategy. Cigarette smoke contains a wide range of chemicals which are hazardous to human health. Some of these chemicals have already proven to be carcinogenic. Because of its high specific surface area GDSEL 651 has showed that it has well adsorption capacity and kinetics in the removal of odorous compounds such as dimethyl sulfide and ethylene in gas phase in both static and dynamic conditions. The reduction of chemicals in cigarette smoke using cigarette filters that are built manually having single layer, double layers and three layers of activated carbon cloth is monitored by GC-MS. The flow rate of cigarette smoke is 2.48 LPM. With three layers at this flow rate nicotine in cigarette smoke is decreased to zero. As a result, activated carbon cloth has proven to filter harmful substances effectively in cigarette smoke before entering the body during smoking. Such filter media has the ability to remove many chemicals in the air and has potential for many other air purification applications.
