Abstract
Adsorption properties of heavy metals and organics in the mixed packed column of scoria and activated carbon, as well as physicochemical properties and functional groups of scoria were investigated. As the mixing ratio of scoria increased, the average removal ratios of cadmium, nickel, chromium, and lead ions increased, but that of benzene and toluene decreased. The mixed packed column of scoria and activated carbon could be effectively used for the simultaneous removal of heavy metals and organics. Scoria has Si-H and Si-O functional groups, and it was confirmed that Si-O functional groups greatly contributed to the adsorption of heavy metals.
