Özet

Metal chloride-impregnated seaweed bio-chars, derived from waste algae (Enteromorpha), are served as solidsorbents for Hg0capture from simulated flue gas. The impacts of various metal chloride modification on Hg0removal performance, i.e. FeCl3, CuCl2, ZnCl2, CoCl2, and CeCl3, are studied. The results display that the Hg0removal performances of Enteromorpha derived bio-chars are greatly enhancedby immersing metal chlorides.FeCl3-and CeCl3-modified bio-chars exhibits the optimal Hg0removal performance. Oxygen and NO show apromotionaleffectonHg0removal,whereasH2OsuppressesHg0adsorption.LowerconcentrationofSO2favorsHg0removal, but higher concentration of SO2inhibits Hg0adsorption. Hg0is oxidized by covalent chloridegroups and metal oxides on the metal chloride-impregnated bio-chars.
