![]() ![]() This means they can easily evaporate into the air, often emitting a noticeable odor. Volatile Organic Compounds (VOCs) are a group of organic chemicals that have a high vapor pressure at room temperature. ![]() It’s like a sponge for impurities, ensuring cleaner, purer environments.” Sources of VOCs in Homes ![]() Quote: “Activated carbon works because contaminant molecules stick to it, not just on the surface but throughout its inner porous layers. When certain chemicals pass next to the carbon surface, they attach to it and are trapped, effectively removing them from the circulating air or water. The vast surface area of activated carbon provides countless bonding sites. Unlike absorption where one substance is taken into another, adsorption involves the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. The magic behind activated carbon’s effectiveness lies in its adsorption capability. Mechanism: How Contaminants Stick to Activated Carbon This process removes water, methane, and tar, leaving behind a porous carbon structure. The creation process involves heating carbon-rich materials, such as wood, coconut shells, or sawdust, in a low-oxygen environment. This enhancement allows it to adsorb a vast amount of contaminants from gases or liquids. Activated carbon, often referred to as activated charcoal, is a specially processed form of carbon that has been treated to increase its surface area. ![]()
