Mechanism of using activated carbon to improve indoor air quality - Database & Sql Blog Articles

Indoor air quality has become a growing concern as modern living environments increasingly rely on air conditioning systems to maintain comfort. While these systems provide temperature and humidity control, they also contribute to poor indoor air quality by reducing natural ventilation. This can lead to "sick building syndrome," where occupants experience symptoms like headaches, dry skin, and respiratory issues due to the accumulation of pollutants. The main pollutants found indoors include particulate matter, tobacco smoke, asbestos, radon, formaldehyde, volatile organic compounds (VOCs), carbon monoxide, carbon dioxide, microorganisms, allergens, and ozone. These substances often come from building materials, furniture, cleaning products, and even human activities such as cooking or smoking. To improve indoor air quality, ventilation is commonly used, but it can be inefficient in areas with high outdoor pollution. Filters are also employed, but most only remove large particles and do not effectively target gases or bacteria. Activated carbon filters have emerged as a promising solution due to their ability to adsorb low concentrations of harmful gases, making them ideal for improving indoor air quality. Activated carbon has a long history of use, dating back to ancient times when charcoal was used to absorb odors. In modern applications, activated carbon is widely used in gas masks, industrial filtration, and air purification systems. Its unique structure, characterized by a vast network of micropores, allows it to trap a wide range of contaminants, including VOCs, gases, and even certain metals. The effectiveness of activated carbon depends on its pore structure, surface chemistry, and the presence of heteroatoms like oxygen and hydrogen. These elements enhance its adsorption capacity and allow it to interact with polar molecules more efficiently. Different types of activated carbon, such as powdered, granular, and fibrous forms, are used depending on the application and desired performance. In addition to physical adsorption, activated carbon can also engage in chemical adsorption, where contaminants react with the surface of the carbon. This makes it particularly effective for removing toxic substances. However, over time, the adsorption capacity of activated carbon diminishes, requiring regeneration or replacement. Overall, activated carbon plays a vital role in maintaining clean and healthy indoor air. As technology advances, improvements in activated carbon filter design and material selection are expected to enhance its efficiency and reduce costs, making it more accessible for widespread use in residential and commercial settings.
