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,
Environment, the protection of human health, regulate the ambient air lead monitoring methods, the development of this standard.
This standard specifies the determination of lead in ambient air by graphite furnace atomic absorption spectrophotometry.
This standard is the "ambient air lead determination of graphite furnace atomic absorption spectrophotometry (provisional)" (HJ 539-2009)
The revision.
This standard was first published in.2009, the original standard drafting unit for the Beijing Environmental Protection Monitoring Center. This is the first
The main contents of the amendment are as follows.
- choose a more appropriate filter;
- increased the microwave digestion of the pre-treatment and improve the digestion of the hot plate digestion conditions, changing the digestion with acid;
- Increased interference cancellation and quality assurance and quality control.
From the date of implementation of this standard, the original standard "Determination of ambient air lead graphite furnace atomic absorption spectrophotometry (temporary)"
(HJ 539-2009).
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 Fengtai District Environmental Monitoring Station, Beijing Yanqing County Environmental Monitoring Station, Beijing Miyun
District Environmental Monitoring Station, Beijing China Measurement North Detection Technology Co., Ltd., Beijing Fangshan District Environmental Monitoring Station, Beijing Environmental Protection
Monitoring center.
The Environmental Protection Department of this standard approves on November 20,.2015.
This standard is implemented as of December 15,.2015.
This standard is explained by the Ministry of Environmental Protection.
Ambient air - Determination of lead - Graphite furnace atomic absorption spectrophotometric method
1 Scope of application
This standard specifies the determination of lead in ambient air by graphite furnace atomic absorption spectrophotometry.
This standard applies to the determination of lead in ambient air.
Collect the ambient air 10 m3 (standard state), the sample volume to 50 ml, the detection limit of 0.009 μg/m3,
The lower limit of determination was 0.036 μg/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
For this standard.
Ambient air - Determination of total suspended particulates - Gravimetric method GB/T
Technical specification for manual monitoring of ambient air quality
Technical requirements and testing methods for HJ/T 374 total suspended particulate matter sampler
3 Principle of the method
With quartz fiber and other filters to collect ambient air particles in the sample, after digestion, into the graphite furnace atomizer,
After drying, ashing and atomization, the ground state atoms of 283.3 nm at the line of selective absor
