Foreword 
This standard is formulated to implement the “Environmental Protection Law of the
People's Republic of China” and “Law of the People's Republic of China on the Prevention
and Control of Atmospheric Pollution”; protect the environment; guarantee human health;
and stipulate the monitoring methods of sulfuric acid mist in exhaust gas of stationary
pollution source.
This standard specifies the ion chromatography for determining the sulfuric acid mist in
stationary source emission.
This standard is organized and formulated by Department of Science, Technology and
Standards of Ministry of Environmental Protection of the People’s Republic of China.
Main drafting organization of this standard. Beijing Municipal Environmental Monitoring
Center.
This standard was approved by Ministry of Environmental Protection on December 30,
2009.
The standard shall be implemented on April 1, 2010.
The Ministry of Environmental Protection is responsible for the interpretation of this
standard.
Stationary source emission - Determination of sulfuric
acid mist - Ion chromatography (on trial)
1  Scope of application 
This standard specifies the ion chromatography for determining the sulfuric acid mist in
stationary source emission
This standard applies to the determination of sulfuric acid mist in the stationary source
emission.
For the organized emission, when the filter cartridge is used for preparing 250mL sample,
the detection limit of this method is 0.12µg/mL; when sample volume is 400L, the
detection limit is 0.08mg/m3, the lower limit of determination is 0.3mg/m3, and the upper
limit of determination is 500mg/m3.
For the fugitive emission, when the filter membrane is used for preparing 250mL sample,
the detection limit of this method is 0.12µg/mL; when sample volume is 3m3, the detection
limit is 0.01mg/m3, and the lower limit of determination is 0.04mg/m3.
2  Normative references 
The articles contained in the following documents have become part of this standard when
they are quoted herein. For the undated documents so quoted, the latest editions shall be
applicable to this standard.
GB/T 16157 The determination of particulates and sampling methods of gaseous
pollutants emitted from exhaust gas of stationary source
HJ/T 55 Technical guidelines for fugitive emission monitoring of air pollutants
HJ/T 373 Technical specifications of quality assurance and quality control for
monitoring of stationary pollution source (on trial)
3  Method and principle 
In this method, glass fiber filter cartridge or quartz fiber filter cartridge is used for collecting
particulate matter sample in organized emission; superfine glass fiber filter membrane or
quartz fiber filter membrane is used for collecting particulate matter in fugitive emission.
Use water to extract. After removing the metal cation through pre-treatment column, inject
the sample into ion chromatograph. Determine the nature in accordance with the retention
sampling point inside the exhaust funnel for isokinetic sampling. Appropriately select
sampling time according to the concentration of sulfuric acid mist. Meanwhile, determine
the necessary temperature, pressure and other parameters. After sampling, carefully take
out filter cartridge. Place it into 250mL ground conical flask with stopper. Rinse the
sampling mouth and elbow with a little of distilled water. Collect and combine the cleaning
lotion into the conical flask. Cover up the flask with stopper. Bring it back to laboratory. Dry
the sampling mouth with cotton swab. Dry the elbow with suction bulb for standby. During
each sampling, at least three filter cartridges of samples shall be collected; take their
average value.
7.1.2 Fugitive emission
It shall be implemented in accordance with HJ/T 55 “Technical Guidelines for Fugitive
Emission Monitoring of Air Pollutants”. Use the medium-volume particulate matter sampler
equipped with filter membrane to collect particulate matter sample at 100L/min for 30min.
If the concentration of sulfuric acid mist is too low, the sampling time can be extended
appropriately. In order to eliminate the interference of background sulfate from ambient air,
reference point shall be set up at upwind direction of fugitive emission; and ambient
background sample shall be collected at the same time under the same conditions.
Record the sampling conditions.
7.2 Sample preservation
The sample in the filter cartridge is put into the ground conical flask with stopper, after
collection. The filter membrane sample is folded to put into the clean paper bags for
preservation, after collection.
7.3 Sample preparation
Select any one of the following sample preparation methods.
7.3.1 Ultrasonic extraction method
Cut the samples collected in (7.1) (be sure not to shake off dust particles). Place them into
a 250mL ground conical flask with stopper. Add 150mL of deionized water for immersing.
