Abstract

Abstract: Technology of preparing activated carbon from corn stalks with ZnCl₂ assisted by microwave irradiation was studied.The optimum technology was obtained through orthogonal test. The product was applied to absorb formaldehyde and compared with marketed activated carbon. When concentration of formaldehyde was 1.94-1.97 mg/m³, penetration time（t_B) of this activated carbon was 12 min which was 20% higher than that of marketed activated carbon, and the speed of adsorption was also faster.

Key words: corn stalks, microwave, activated carbon, formaldehyde
