Ministry of Environmental Protection released seven instruments such as mass spectrometry standards

Information

In order to implement the Law of the People's Republic of China on Environmental Protection and the Law of the People's Republic of China on Prevention and Control of Water Pollution, protect the environment, safeguard human health and standardize the environmental monitoring work, the "Determination of Anilines in Water Quality by Gas Chromatography-Mass Spectrometry" was approved and released.

  

Standard names, numbers are as follows:

1 "water quality aniline compounds Determination of gas chromatography - mass spectrometry HJ 822-2017";

2 " water quality Determination of cyanide flow injection - spectrophotometry (HJ 823-2017)";

3 water quality the determination of sulfide flow injection - methylene blue spectrophotometry (HJ 824-2017) ";

4 " water quality Determination of volatile phenol injection flow -4-amino-antipyrine spectrophotometry (HJ 825-2017)";

5 " water quality Determination of anionic surfactant flow injection - methylene blue spectrophotometry (HJ 826-2017)";

6 "Water quality carbamates pesticides determination by ultra performance liquid chromatography - triple quadrupole mass spectrometry (HJ 827-2017)";

7 " water quality Determination of chemical oxygen demand dichromate method (HJ 828-2017 instead of GB 11914-89)".

The above standards will come into force on May 1, 2017 and will be published by China Environmental Press. The standard content can be found on the MEP website.

Since the implementation of the above standards,the "Determination of chemical oxygen demand water quality dichromate" (GB 11914-89) the original State Environmental Protection Agency approved and released on December 25, 1989 was abolished.
