Scope

This standard specifies the ion chromatography method for sulfuric acid mist in waste gas from fixed pollution sources. This standard is applicable to the determination of sulfuric acid mist in waste gas from fixed pollution sources. For organized exhaust gas, when the filter cartridge is prepared into a 250ml sample, the detection limit of this method is 0.12μg/ml. When the sampling volume is 400L, the detection limit is 0.08mg/m, and the lower limit of determination is 0.3mg/m. The upper limit of determination is 500mg/m. For unorganized exhaust gas, when the filter membrane is prepared into a 250ml sample, the detection limit of this method is 0.12μg/ml. When the sampling volume is 3m, the detection limit is 0.01mg/m, and the lower limit of determination is 0.04mg/m.
