3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Polycyclic aromatic hydrocarbons (polycyclicaromatichydrocarbons); PAHs
a series of hydrocarbon compounds and their derivatives fused by two or more benzene rings, which may also have short alkyl or naphthenic rings.
Base substituent.
4 Principle
The polycyclic aromatic hydrocarbons in the sample were ultrasonically extracted using n-hexane as an extraction solvent. Gas chromatography-mass spectrometer after constant volume extraction
(GC/MS) was tested and quantified by external standard method.
Note. Other approved suitable solvents can also be selected as the extraction solvent.
5 reagents and materials
Unless otherwise specified, only reagents identified as analytically pure and of the above purity were used in the analysis.
5.1 n-hexane. chromatographically pure.
5.2 Polycyclic aromatic hydrocarbon calibration compounds (see Table A.1). mass fraction not less than 99%.
5.3 Mixed standard stock solution. about.200μg/mL, weigh about 0.02g of each polycyclic aromatic hydrocarbon calibration compound (5.2), accurate to 0.1mg,
Place in a 100 mL volumetric flask (6.6) and dilute to the mark with n-hexane (5.1). The standard stock solution is stored in the dark below 4 ° C, effective
