标准范围
ISO 17072-1:2011规定了一种测定皮革中可萃取金属的方法,使用酸性人工汗液萃取,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/原子发射光谱法(ICP/AES)或电感耦合等离子体/质谱法(ICP/MS)进行测定,或原子吸收光谱法(AAS)或原子荧光光谱法(SFA)。该方法特别适用于铬鞣革中可萃取铬的测定。该方法测定皮革中的可提取金属,它不是化合物-特定于或特定于金属的氧化状态。该方法也适用于许多可萃取金属的测定,包括铝(Al)、锑(Sb)、砷(As)、钡(Ba)、镉(Cd)、钙(Ca)、铬(Cr)、钴(Co)、铜(Cu)、铁(Fe)、铅(Pb)、镁(Mg)、锰(Mn)、汞(Hg)、钼(Mo)、镍(Ni)、钾(K)、硒(Se)、锡(Sn)、钛(Ti)、锌(Zn),和锆。可提取铅的定量限为3 mg/kg。
ISO 17072-1:2011 specifies a method for the determination of extractable metals in leather using extraction with an acid artificial-perspiration solution and subsequent determination with inductively coupled plasma/optical emission spectrometry (ICP-OES), or inductively coupled plasma/atomic emission spectrometry (ICP/AES), or inductively coupled plasma/mass spectrometry (ICP/MS), or atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).This method is especially suitable for determining the extractable chromium in chromium tanned leathers.This method determines extractable metals in leather, it is not compound-specific or specific to the oxidation state of the metals.This method is also applicable for the determination of many extractable metals, including 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), tin (Sn), titanium (Ti), zinc (Zn), and zirconium (Zr).The quantification limit of extractable lead is 3 mg/kg.
