Leather - Chemical determination of metal content - Part 1: Extractable metals (ISO 17072-1:2011); German version :2011
 N EN ISO 17072-1

Annotation

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)

Antimony (Sb)

Arsenic (As)

Barium (Ba)

Cadmium (Cd)

Calcium (Ca)

Chromium (Cr)

Cobalt (Co)

Copper (Cu)

Iron (Fe)

Lead (Pb)

Magnesium (Mg)
