摘要：
In treating exhaust gases containing SO.sub.2, HCl and HF, there is disclosed a method of treating such exhaust gas which comprises detecting the amounts of HCl and HF in the exhaust gas and supplying an amount of a magnesium compound commensurate with a stoichiometric amount to become at least MgCl.sub.2 and MgF.sub.2 in an exhaust-gas treating tower and a calcium compound as a SO.sub.2 solvent into the exhaust-gas treating tower.The aforesaid method of treating an exhaust gas comprises a method of causing Mn ion to coexist in an absorbing solution in contact with the exhaust gas.
