Formaldehyde is a common emission from furniture and indoor decorations. Although the concentration of formaldehyde gas is not too high in the indoor environment, it is highly toxic and carcinogenic. The formaldehyde removal potential of a novel type of green and safe nano-porous materials, Metal-Organic Frameworks (MOFs), with a high surface-to-volume ratio, strong adsorption capacity, and low regeneration temperature was investigated. To date, researchers are mainly focusing on formaldehyde selectivity and detection using MOFs in low moisture circumstances. This study carried out a series of experiments to compare breakthrough curves of formaldehyde dynamic adsorption on MIL-100(Fe), MIL-160(Al), and aluminum fumarate with activated carbon. In experiments, the formaldehyde was evaporated from diluted formalin solution, dried to 30±5 % RH, and driven through different adsorbents by nitrogen. The results indicated that MOFs showed great potential for indoor air formaldehyde removal.
