本标准规定了测定固定污染源废气中硫酸雾的离子色谱法。
本标准适用于固定污染源废气中硫酸雾的测定。
测定有组织排放废气，当采样体积为0.40 m3（标准状态），定容体积为100 ml，进样体积为25 μl 时，方法检出限为0.2 mg/m3，测定下限为0.80 mg/m3。测定无组织排放废气，当采样体积为3.0 m3（标准状态），定容体积为50.0 ml，进样体积为25 μl 时，方法检出限为0.005mg/m3，测定下限为0.020 mg/m3。

Scope

This standard specifies an ion chromatography method for the determination of sulfuric acid mist in waste gas from stationary pollution sources. This standard is applicable to the determination of sulfuric acid mist in waste gas from fixed pollution sources. To measure organized exhaust gas, when the sampling volume is 0.40 m3 (standard state), the fixed volume is 100 ml, and the injection volume is 25 µl, the method detection limit is 0.2 mg/m3 and the lower determination limit is 0.80 mg/m3. To measure fugitive exhaust gas, when the sampling volume is 3.0 m3 (standard state), the constant volume is 50.0 ml, and the injection volume is 25 µl, the detection limit of the method is 0.005 mg/m3, and the lower determination limit is 0.020 mg/m3. 2
