announcement
No. 77 of.2010
In order to implement the "Environmental Protection Law of the People's Republic of China", protect the environment, and protect human health, we now approve the measurement of ambient air ozone.
Six standards, such as the fixed ultraviolet photometry, are national environmental protection standards and are released.
The standard name and number are as follows.
2. Determination of water quality pentachlorophenols by gas chromatography (HJ 591-2010);
3. Determination of water quality nitrobenzene compounds by gas chromatography (HJ 592-2010);
4. Determination of water quality, elemental phosphorus, phosphorus molybdenum blue spectrophotometry (provisional) (HJ 593-2010);
5. Determination of the total amount of water-based developer and its oxides - Iodine-starch spectrophotometry (interim) (HJ 594-2010);
6. Determination of the total amount of water color developing agent 169 Coupler spectrophotometry (provisional) (HJ 595-2010).
The above standards have been implemented since January 1,.2011 and published by the China Environmental Science Press. The standard content can be found on the website of the Ministry of Environmental Protection.
From the date of implementation of the above standards, the following three national environmental protection standards approved and issued by the former National Environmental Protection Agency shall be abolished.
The name and number are as follows.
1. Determination of ambient air ozone by ultraviolet spectrophotometry (GB/T 15438-1995);
2. Determination of water quality pentachlorophenols by gas chromatography (GB 8972-88);
3. Determination of Total Nitro Compounds in Industrial Wastewater Gas Chromatography (GB 4919-85).

Foreword
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 Air Pollution, protect the environment and protect people
This standard is formulated for the health of the body and the monitoring method for the regulation of ozone in the ambient air.
This standard specifies the ultraviolet photometric method for the determination of ozone in ambient air.
This standard is a revision of the "Measurement of Ambient Air Ozone by Ultraviolet Spectrophotometry" (GB/T 15438-1995).
This standard was first published in.1995. The original standard drafting unit was the Anshan Environmental Monitoring Center Station. This is the first revision. Revision
The main contents are.
-- Revised the scope of application of ozone determination in air and its reference conditions.
-- Revised the "Interference and Elimination" clause.
- The physical meaning of the representatives in the formula ln(I/I0) = −aρd is clearly defined. The formula for calculating the ozone concentration has been increased.
-- Added terms and definitions.
-- Added quality assurance and quality control provisions.
-- Supplementary and complete the technical conditions and precautions for testing.
-- Added requirem
