HJ 822-2017 (English Version) PDF

Scope: This standard specifies the gas chromatography-mass spectrometry method for the determination of 19 aniline compounds in water. This standard is applicable to the determination of aniline compounds in surface water, groundwater, seawater, domestic sewage and industrial wastewater. The 19 kinds of aniline compounds include aniline, 2-chloroaniline, 3-chloroaniline, 4-chloroaniline, 4-bromoaniline, 2-nitroaniline, 2,4,6-trichloroaniline, and 3,4-dichloro Aniline, 3-nitroaniline, 2,4,5-trichloroaniline, 4-chloro-2-nitroaniline, 4-nitroaniline, 2-chloro-4-nitroaniline, 2,6-dichloro -4-nitroaniline, 2-bromo-6-chloro-4-nitroaniline, 2-chloro-4,6-dinitroaniline, 2,6-dibromo-4-nitroaniline, 2,4 -Dinitroaniline, 2-bromo-4,6-dinitroaniline. After verification, this method can also be used for other aniline compounds. When the sampling volume is 1000ml and the concentration volume is 1.0ml, the detection limit of the method is 0.05μg/L~0.09μg/L, and the lower limit of determination is 0.20μg/L~0.36μg/L. See Appendix A for details.
