ACTIVE CARBON HAVING HEAVY METAL-ABSORBING ABILITY AND ITS PREPARATION METHOD

摘要

The present invention relates to improving the adsorption performance of activated carbon, and more particularly, to a method for producing activated carbon having excellent heavy metal adsorption capacity, characterized in that the activated carbon is heat-treated at 130-350 ° C. for 1-20 hours. It also relates to the adsorption treatment of wastewater containing heavy metals harmful to humans.
