【Abstract】 In power plants, the by products of flue gas desulfuration by LIFAC technology is solid materials. The anions in the eluate of these materials showered by rain have negative influence on the environment. The conventional methods for detecting these anions are colorimetry and gravimetry. This paper uses ion chromatography to determine the anions (F -, CI - and SO 4 2- ) in the eluate of the solid waste. The RSDs are 13.5%, 5.1% and 0.67%, and the recoveries are 93.2%～99.8%, 93.8%～101.7% and 95.2%～101.2% for F -, Cl - and SO 4 2- , respectively.更多还原
