标准范围

ISO 17072-2:2011规定了一种皮革中总金属含量的测定方法，该方法使用皮革的消解，然后使用电感耦合等离子体/光发射光谱法（ICP/OES）、电感耦合等离子体/质谱法（ICP/MS）、原子吸收光谱法（AAS）或原子荧光光谱法（SFA）进行测定。该方法测定皮革中的总金属含量；它不是特定于化合物或特定于金属的氧化状态。本方法适用于铝、锑、砷、钡、镉、钙、铬、钴、铜、铁、铅、镁、锰、汞、钼、镍、钾、硒、硅、钠、锡、钛、锌、锆的测定。总铅的定量限为8 mg/kg。ISO 17072-2:2011不适用于铬鞣革。在这种情况下，使用ISO 5398-1、ISO 5398-2、ISO 5398-3或ISO 5398-4。

ISO 17072-2:2011 specifies a method for the determination of the total metal content in leather using digestion of the leather and subsequent determination with inductively coupled plasma/optical emission spectrometry (ICP/OES), or inductively coupled plasma/mass spectrometry (ICP/MS), or atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).This method determines the total metal content in leather; it is not compound-specific or specific to the oxidation state of the metals.The method is applicable for determining aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), potassium (K), selenium (Se), silicon (Si), sodium (Na), tin (Sn), titanium (Ti), zinc (Zn), and zirconium (Zr).The quantification limit of total lead is 8 mg/kg.ISO 17072-2:2011 is not applicable to chromium-tanned leathers. In this case, ISO 5398-1, or ISO 5398-2, or ISO 5398-3, or ISO 5398-4 are used.
