标准范围

This part of ISO 17072 specifies a method for the determination of extractable metals in leather usingextraction with an acid artificial-perspiration solution and subsequent determination with inductively coupledplasma/optical emission spectrometry (ICP-OES), or inductively coupled plasma/atomic emissionspectrometry (ICP/AES), or inductively coupled plasma/mass spectrometry (ICP/MS), or atomic absorptionspectrometry (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 oxidationstate of the metals.The 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)Zirconium (Zr)The quantification limit of extractable lead is 3 mg/kg (see Annex A).
