The adsorption of acetaldehyde from air using various activated carbon and carbon fibers was investigated in this study. These adsorbents included activated carbon (AC), carbon fibers (CFs), activated carbon fibers (ACFs), and metal-coated carbon fibers (MCCFs) supplied by different manufacturers. AC was categorized as AC₁, AC₂, AC₃, and AC₄, CFs were denoted as ACF₁, while ACFs and MCCFs were expressed as ACF₂ and ACF₃, respectively. Five composite materials were prepared using the AC and ACFs in different ratios, and experiments were conducted to assess their acetaldehyde adsorption efficiency under dry and wet conditions. The results showed that the acetaldehyde adsorption efficiency of an impregnated AC₄ was higher (95.9%) than that of both non-impregnated AC₁ and AC₃ and an impregnated AC₂ after 1 min of operation. ACF₂ showed a higher acetaldehyde adsorption efficiency (50.9%) as compared to ACF₁ and ACF₃ because of its larger surface area and selective absorption capability after 1 min of operation. A composite material comprising 6.3 g of AC₄ and 1 g of ACF₂ showed the highest adsorption efficiency of 97.9% under dry conditions. However, this adsorption efficiency significantly decreased under wet conditions.
