Removal of Formaldehyde Using the Aminated Activated Carbon by Etilenodiamina

In order to remove formaldehyde efficiently, the activated carbon was oxidized by nitric acid and then modified by etilenodiamina. The carbon treated with nitric acid and etilenodiamina showed the significant differences in IR spectrum compare with original activated carbon. The adsorption capacity for the formaldehyde of prepared carbon and original carbon were 2.4 mg/g and 1.0 mg/g, respectively. Results demonstrate that the amino group on carbon might improve the adsorption performance of carbon for formaldehyde.
