A set of simulation equipment is set up after the conditions of removing SO 2 and heavy metal Hg (Hg 0 and Hg 2+ ) has been investigated, the results of the removal technology method of absorption Hg 0 , Hg 2+ in smelting gases containing SO 2 with (NH 4 ) 2 S is tested, and their composition of reaction products and sediment are analyzed with XRD and XPS. Obtained that: when absorption concentration of (NH 4 ) 2 S are 0.8 mol/L, in pH 7.0-3.0 removal efficiency of Hg 0 and SO 2 is higher,doi:10.2991/icseee-15.2016.68 fatcat:4dllxnq4xnc4fpqseivu5q6txe
