Preface
In order to implement the Environmental Protection Law of the People's Republic of China and the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution,
The protection of human health, regulate the ambient air and waste gas in the determination of hydrogen chloride, the development of this standard.
This standard specifies the determination of ambient air and hydrogen chloride in waste gas by ion chromatography.
This standard is the "ambient air and waste hydrogen chloride determination of ion chromatography (provisional)" (HJ 549-2009) repair
Set.
This standard was first published in.2009, the original standard drafting unit for the Beijing Environmental Protection Monitoring Center. This time for the first time
The main contents of the amendments and amendments are as follows.
- revised method limits, reagents and materials, instruments and equipment, sample collection, analysis steps, results calculations
With the express clause.
- complements the principle of the method, quality assurance and quality control part of the content.
- Added warnings, terms and definitions, interference and elimination, precision and accuracy, and cautionary terms.
From the date of implementation of this standard, the original standard "Determination of ambient air and waste hydrogen chloride ion chromatography (provisional)" (HJ
549-2009).
This standard is organized by the Ministry of Environmental Protection Science and Technology Standards Division.
The drafting of this standard. Beijing Environmental Protection Monitoring Center.
The standard verification unit. Jiangsu Province Environmental Monitoring Center, Peking University Environmental Engineering Laboratory, Beijing physical and chemical analysis
Center, Beijing Environmental Protection Monitoring Center, Beijing Haidian District Environmental Protection Bureau Monitoring Station and Beijing Fangshan District Environmental Protection
Monitoring station.
The environmental protection department of this standard approved on May 13,.2016.
This standard has been implemented since August 1,.2016.
This standard is explained by the Ministry of Environmental Protection.
Ambient air and waste gas - Determination of hydrogen chloride - Ion chromatographic method
WARNING. Hydrogen chloride is harmful to the human body. When sampling, wear protective equipment in a sampling environment to avoid inhalation or contact with skin
And eyes.
1 Scope of application
This standard specifies the determination of ambient air and hydrogen chloride in waste gas by ion chromatography.
This standard applies to the determination of hydrogen chloride in ambient air and waste gas.
For ambient air, when the sampling volume is 60 L (standard state) and the volume of volume is 10.0 ml, the detection limit is
0.02 mg/m3, the determination of the lower limit of 0.080 mg/m3.
For the fixed source of waste gas, when the sampling volume of 10 L (standard state), the volume of volume is 50.0 ml, the method check
Limit of 0.2 mg/m3, the determination of the lower limit of 0.80 mg/m3.
