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,
Protection of human health, regulate the fixed source of waste gas in the determination of hydrogen chloride, the development of this standard.
This standard specifies the silver nitrate volumetric method for the determination of hydrogen chloride in the waste of fixed sources.
This standard is the "fixed source of waste gas hydrogen chloride determination of silver nitrate capacity (temporary)" (HJ 548-2009) of the
Revised.
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 of reagents and materials, instruments and equipment, sample collection and analysis steps.
- complements the interference and elimination and quality assurance and quality control parts.
- Increased precision, accuracy, result representation and waste disposal terms.
Since the implementation of the standard date, the original standard "fixed sources of waste gas hydrogen chloride determination of silver nitrate capacity (temporary)"
(HJ 548-2009).
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. Beijing Physical and Chemical Analysis and Testing Center, Peking University Environmental Engineering Laboratory, Beijing Fangshan District
Environmental Protection Monitoring Station, Beijing Haidian District Environmental Protection Bureau Monitoring Station, Jiangsu Province Environmental Monitoring Center, Beijing Environmental Protection
Monitoring center.
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.
Determination of hydrogen chloride in fixed sources - Silver nitrate volumetric 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. Nitric acid used in the experiment has strong oxidizing and corrosive, the operation should wear protective equipment, solution preparation and sample
The pretreatment process should be carried out in a fume hood.
1 Scope of application
This standard specifies the silver nitrate volumetric method for the determination of hydrogen chloride in the waste of fixed sources.
This standard is applicable to the determination of hydrogen chloride in waste gas from fixed sources.
When the sampling volume is 15 L (standard state), the detection limit is 2 mg/m3 and the determination limit is 8.0 mg/m3.
2 normative reference documents
The contents of this standard refer to the following documents or their terms. Those who do not specify the date of the reference file, the effective version of the appropriate
