METHOD FOR PREPARING CARBON FOAM FOR HEAVY METAL ADSORPTION

摘要

Disclosed is a method for preparing a carbon foam for heavy metal adsorption, according to the present invention, comprising: a mixture preparation step of preparing a mixture by mixing a phenolic resin and a polyvinyl alcohol aqueous solution; a foaming step of mixing a foaming agent and the mixture prepared through the mixture preparation step, and foaming the same; a curing step of mixing a curing agent and the mixture foamed through the foaming step, and curing the same; a molding step of injecting the mixture cured through the curing step into a mold, and molding the same; and a carbonization step of injecting the molded product molded through the molding step into a carbonization furnace, and carbonizing the same by injecting an inert gas while heating the same. The carbon foam for heavy metal adsorption prepared by the steps has a low electrical resistance value, and thus exhibits remarkable adsorption capacity for heavy metals when applied to an electrolysis device.
