HJ 784-2016 in English

本标准规定了测定土壤和沉积物中多环芳烃的高效液相色谱法。
本标准适用于土壤和沉积物中16 种多环芳烃的测定，包括萘、苊烯、苊、芴、菲、蒽、荧蒽、芘、苯并(a)蒽、.、苯并(b)荧蒽、苯并(k)荧蒽、苯并(a)芘、二苯并(a, h)蒽、苯并(g,h,i)�、茚并(1,2,3-c,d)芘。
当取样量为10.0 g，定容体积为1.0 ml 时，用紫外检测器测定16 种多环芳烃的方法检出限为3 μg/kg～5 μg/kg，测定下限为12 μg/kg～20 μg/kg；用荧光检测器测定16 种多环芳烃的方法检出限为0.3 μg/kg～0.5 μg/kg，测定下限为1.2 μg/kg～2.0 μg/kg。详见附录A。

Scope

This standard specifies a high-performance liquid chromatography method for the determination of polycyclic aromatic hydrocarbons in soil and sediments. This standard is applicable to the determination of 16 polycyclic aromatic hydrocarbons in soil and sediments, including naphthalene, acenaphthylene, acenaphthylene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(A)anthracene,..., benzo(B) Fluoranthene, benzo(K)fluoranthene, benzo(A)pyrene, dibenzo(A,H)anthracene, benzo(G,H,I)perylene, indeno(1,2,3-C, D)Pyrene. When the sampling volume is 10.0 G and the fixed volume is 1.0 ML, the detection limit of 16 kinds of polycyclic aromatic hydrocarbons using a UV detector is 3 MG/KG ~ 5 MG/KG, and the lower detection limit is 12 MG/KG ~ 20 MG/KG; the detection limit of 16 polycyclic aromatic hydrocarbons measured with a fluorescence detector is 0.3 MG/KG ~ 0.5 MG/KG, and the lower limit of determination is 1.2 MG/KG ~ 2.0 MG/KG. See Appendix A for details.
