1 Scope
This part of ISO 17072 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.
The method is also applicable for the determination of many extractable metals, including:
Aluminium (Al)
Copper (Cu)
Nickel (Ni)
Antimony (Sb)
Iron (Fe)
Potassium (K)
