Leather - Chemical determination of metal content - Part 1: Extractable metals

PUBLISH DATE 2019
ISO 17072-1:2019

This document 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),
  • inductively coupled plasma mass spectrometry (ICP-MS),
  • atomic absorption spectrometry (AAS), or
  • spectrometry of atomic fluorescence (SFA).

This method determines extractable metals in leather; it is not compound-specific or specific to the oxidation state of the metals.

This method is especially suitable for determining the extractable chromium in chromium-tanned leathers.
