Research on Activated Carbon to Adsorption of formaldehyde

By influential experiment on production technology of activated carbon for formaldehyde adsorption,the contrasting experiment on adsorption of formaldehyde with activated carbon,as well as on the application of activated carbon to indoor air purification,the result have shown that the adsorption amount of formaldehyde of the new-variety activated carbon is 4 times of that of bamboo charcoal and 1.5 times of that of coconut charcoal.90.6% of formaldehyde can be adsorbed through dynamic way,able to reach to the national indoor air quality standard for formaldehyde(0.10 g·m-3) when this activated carbon is used in air purification indoors.The static adsorption and dynamic adsorption experiments have also shown that activated carbon can make air flow,and therefore,the new product is advantageous to removal of formaldehyde and cleaning of indoor air.
