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 fixed source of waste gas in the form of particulate matter and the determination of arsenic and its compounds,
Develop this standard.
This standard specifies the determination of fixed sources of waste gas in the form of particulate matter and its compounds of diethyldisulfide
Substituted carbamate spectrophotometric method.
This standard is for the determination of "ambient air and waste arsenic, silver diethyldithiocarbamate spectrophotometric (provisional)"
(HJ 540-2009).
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.
- According to the scope of application of the standard, the original standard name "Ambient air and arsenic determination of diethyldithioamino
Formic acid silver spectrophotometric method (tentative) "modified to" fixed source of waste gas arsenic determination of diethyldithiocarbamate silver
Spectrophotometry";
- the contents of the ambient air and so on have been removed from the original standard;
- Based on the experimental results, the detection limit was revised from 0.00 μg/m3 to 0.004 mg/m3 and the lower limit of determination was 3.5 μg/m3
Revised to 0.016 mg/m3;
- the collection of samples and the preparation of samples and other content has been revised;
- increased precision and accuracy and other content;
- improve the quality assurance and quality control content;
- Increased waste disposal.
Since the implementation of the standard date, the original standard "Determination of ambient air and arsenic arsenic diethyldithiocarbamate
Photometric method (provisional) "(HJ 540-2009) abolished.
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, Beijing Xicheng District Environmental Protection Monitoring Station.
The standard verification unit. Yunnan Honghe State Environmental Monitoring Station, Beijing Changping District Environmental Protection Monitoring Station, Beijing Feng
Taiwan Environmental Protection Monitoring Station, Beijing Xicheng District Environmental Protection Monitoring Station, Beijing China measured North Detection Technology Co., Ltd.
The environmental protection department of this standard approved on July 26,.2016.
This standard has been implemented since October 1,.2016.
This standard is explained by the Ministry of Environmental Protection.
Determination of arsenic in fixed source
Silver dimethyldithiocarbamate spectrophotometric method
Warning. arsine is a highly toxic gas, before the test must check whether the arsine generator is connected to prevent leakage or reaction
The bottle was disintegrated. The reaction shall be carried out in a fume hood, and the operator shall wear protective equipment.
