ABSTRACT
Objective To develop a remover of formaldehyde in indoor air. Methods Activated carbon was used as the raw materials, potassium hydroxide as the activator. The activated carbon was modified through activation and impregnation. The influence factors for the formaldehyde adsorption property of activated carbons were evaluated, such as the size, activation temperature, activation time and impregnation time. Results The optimum technics conditions for developing the formaldehyde remover and the optimum conditions to absorb formaldehyde were confirmed. The mass adsorption capacity of the adsorbent was 49.6%, the BET surface area was about 1 591 m2/g and the total pore volume was 1.01 cm3/g. Conclusion The mass adsorption capacity of formaldehyde and the BET surface area of the modified activated carbon in the present paper are better than those of unmodified activated carbon.
