ISO 17072-2-2019 皮革--金属含量的化学测定--第2部分：总金属含量 Leather -- Chemical determination of metal content -- Part 2: Total metal content

This document specifies a method for the determination of the total metal content in leather using digestion of the leather 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 the total metal content in leather; it is not compound-specific or specific to the oxidation state of the metals.
