DIN 38414-23-2002 德国对水、废水和淤泥的标准检验方法.淤泥和沉积物(S组).第23部分:高效液相色谱法和荧光检测法测定15多环芳香烃(S23)
German standard methods for the examination of water, waste water and sludge - Sludge and sediments (group S) - Part 23: Determination of 15 polycyclic aromatic hydrocarbons (PAH) by high performance liquid chromatography (HPLC) and fluorescence detection
The document specifies a chemical method for the determination of 15 selected polycyclic aromatic hydrocarbons (PAH) in sludge and sediment with mass fraction wi = 0,05 mg per kg dry solids mT. This method can be used for determination of PAH, which not mentioned in the document, provided that the correctness is covered. Two methods for the preparation of sludge and sediment are described. By method A the original sample and by method B the dried sample is extracted. Afterwards the PAH are separated by HPLC and identified and quantified by fluorescence detection.#,,#
