BS EN 16320:2013+A1:2017规定了测定水中汞含量的方法
王水萃取后的肥料“和石灰材料”,以及通过
蒸汽发生(VG)与原子吸收光谱仪或电感耦合光谱仪耦合
等离子体原子发射光谱仪。预计定量限为0.01 mg/kg。注:肥料一词贯穿于本欧洲标准,包括
石灰材料,除非另有说明。交叉引用:EN 1482-2EN 12944-1:1999EN 12944-2:1999EN 12944-3:2001 EN ISO 3696ISO 36962003/2003/ECEN 1482-1ISO 5725-1ISO 5725-2包含以下内容:修订,2017年3月。修订并替换BS EN 16320:2013
BS EN 16320:2013+A1:2017 specifies a method for the determination of the content of mercury in
fertilizers "and liming materials" after extraction with aqua regia and the detection of mercury by
vapour generation (VG) coupled to an atomic absorption spectrometer or an inductively coupled
plasma-atomic emission spectrometer. A limit of quantification of 0,01 mg/kg is to be expected.NOTE The term fertilizer is used throughout the body of this European Standard and includes
liming materials unless otherwise indicated.Cross References:EN 1482-2EN 12944-1:1999EN 12944-2:1999EN 12944-3:2001EN ISO 3696ISO 36962003/2003/ECEN 1482-1ISO 5725-1ISO 5725-2Incorporates the following:Amendment, March 2017. Amends and replaces BS EN 16320:2013
