LEYVA RAMOS, Roberto et al. Adsorción de Cd(II) en solución acuosa sobre diferentes tipos de fibras de carbón activado. Rev. Soc. Quím. Méx [online]. 2004, vol.48, n.3, pp.196-202. ISSN 0583-7693.

It was studied the adsorption of Cd(II) onto Activated Carbon Fibers (ACF) in the forms of Cloth and Felt, without oxidizing and oxidized with HNO₃. It was found that Cd(II) was adsorbed on the acidic sites and that the Cloth had higher adsorption capacity because it contained greater concentration of acidic sites. The adsorption capacity of the ACF increased with the oxidation since the concentration of acidic sites was increased. The adsorption capacity of the ACF depends upon its textural and physicochemical properties.
