announcement
No. 68 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 "environmental air benzene series"
Five standards, such as solid adsorption/thermal desorption-gas chromatography, are considered as national environmental protection standards and are released.
The standard name and number are as follows.
2. Determination of Benzene in Ambient Air Activated Carbon Adsorption/Carbon Disulfide Desorption - Gas Chromatography (HJ 584-2010);
3. Determination of free chlorine and total chlorine in water, N,N-diethyl-1,4-phenylenediamine titration method (HJ 585-2010);
4. Determination of free chlorine and total chlorine in water - N,N-diethyl-1,4-phenylenediamine spectrophotometric method (HJ 586-2010);
V. "Determination of water quality atrazine by high performance liquid chromatography" (HJ 587-2010).
The above standards have been implemented since December 1,.2010 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 four national environmental protection standards approved and issued by the former National Environmental Protection Agency shall be abolished.
The name and number are as follows.
I. Determination of Air Quality, Toluene, Xylene and Styrene by Gas Chromatography (GB/T 14677-93);
2. Determination of Air Quality Styrene by Gas Chromatography (GB/T 14670-93);
3. Determination of free chlorine and total chlorine in water. N,N-diethyl-1,4-phenylenediamine titration method (GB 11897-89);
4. Determination of free chlorine and total chlorine in water quality N,N-Diethyl-1,4-phenylenediamine spectrophotometric method (GB 11898-89).

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
The body is healthy, and the method for determining the determination of benzene in the air is formulated.
This standard specifies the determination of benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, isopropyl in ambient air and indoor air.
Solid adsorption/thermal desorption of benzene and styrene - gas chromatography.
This standard is a revision of the "Gas Chromatography for the Determination of Air Quality of Toluene, Xylene and Styrene" (GB/T 14677-93).
This standard was first published in.1993. The original standard drafting unit was Shenyang Environmental Science Research Institute. This is the first revision. This repair
The main contents of the subscription are as follows.
-- Revise the standard name to "Determination of Benzene in Ambient Air by Solid Adsorption/Thermal Desorption - Gas Chromatography";
-- The target component is increased from five to eight;
- modifying the standard solution matrix from carbon disulfide
