No. 47 of.2009
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 water quality polycyclic aromatic hydrocarbons.
Eighteen standards, such as fixed liquid extraction and solid phase extraction high performance liquid chromatography, are national environmental protection standards and are released.
The standard name and number are as follows.
I. Determination of Polycyclic Aromatic Hydrocarbons by Liquid-Liquid Extraction and Solid Phase Extraction High Performance Liquid Chromatography (HJ 478-2009);
2. Determination of nitrous oxides (nitrogen oxides and nitrogen dioxide) - Determination of naphthalene diamine hydrochloride spectrophotometric method (HJ 479-
2009);
III. Determination of Fluoride in Ambient Air Filtration of Fluoride Ion Selective Electrode Method (HJ 480-2009);
IV. Determination of fluoride in ambient air Determination of fluoride ion-selective electrode method for lime filter paper (HJ 481-2009);
6. Determination of Sulfur Dioxide in Ambient Air - Tetrachloromercury Salt Absorption - Pararosaniline Spectrophotometry (HJ 483-2009);
VII. Determination of water content cyanide volumetric method and spectrophotometry (HJ 484-2009);
VIII. Determination of copper in water quality by diethyldithiocarbamate spectrophotometry (HJ 485-2009);
IX. Determination of copper in water quality 2,9-Dimethyl-1,10 phenanthroline spectrophotometry (HJ 486-2009);
X. Determination of Fluoride in Water Quality by Spectrophotometric Method of Zirconium Sulfate Sulfate (HJ 487-2009);
XI. Determination of Fluoride in Water Quality Fluorescence Spectrophotometry (HJ 488-2009);
XII. Determination of Silver in Water Quality 3,5-Br2-PADAP Spectrophotometry (HJ 489-2009);
XIII. Determination of Silver in Water Quality by Cadmium Reagent 2B Spectrophotometry (HJ 490-2009);
XIV. Determination of Total Chromium in Soils by Flame Atomic Absorption Spectrophotometry (HJ 491-2009);
15. Air Quality Vocabulary (HJ 492-2009);
