Three activated carbon samples were studied for their removal of gas-phase formaldehyde at low concentrations. One type of activated carbon fiber and two types of granular activated carbon, one of which is manufactured specifically as a formaldehyde control technology, were characterized using X-ray photo-electron spectroscopy before and after formaldehyde adsorption experiments. The granular activated carbon manufactured specifically for formaldehyde removal performed the best at low formaldehyde concentrations, while the adsorption capacity of the activated carbon sample was greater at higher concentrations than that of both granular activated carbon samples. The impact of relative humidity on adsorption capacities of each activated carbon sample was minimal.
