Abstract
A kind of preparation method of activated carbon, includes the following steps：（1）Polyamines polyene is put into beaker, polyamines polyene is one or more in selected from triethylene tetramine, diethylenetriamine；（2）A certain amount of activated carbon is taken to be added in beaker, distilled water, which is added, to be uniformly mixed；（3）By step（2）In mixture heating, obtain activated carbon.The activated carbon adsorptive capacity prepared through the invention is strong, and work efficiency is high, can preferably adsorb formaldehyde and other harmful substances in air.
Description
Technical field
The present invention relates to technical field of air purification, in particular to a kind of preparation methods of activated carbon.
Background technology
The activated carbon generally use normal activated carbon of removal formaldehyde at present, the effect mainly occurred is physical absorption, activity
Charcoal, which substantially reduces its adsorption capacity with regard to adsorption saturation, cannot achieve the purpose that thoroughly to remove formaldehyde.Existing activated carbon PARA FORMALDEHYDE PRILLS(91,95)
Adsorbance it is very low, this adsorption effect is not too apparent.
