ISO 5398-4:2007 Leather - Chemical determination of chromic oxide content - Part 4: Quantification by inductively coupled plasma - optical emission spectrometer (ICP-OES)
This part of ISO 5398 describes a method for the determination of chromium in aqueous solution obtained
from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its
oxidation state.
This method describes the determination of chromium by inductively coupled plasma – optical emission
spectrometry and is applicable to leathers which are expected to have chromic oxide contents in excess of
1 mg/kg. Two techniques for the preparation of the solution to be analysed are included. In the case of
dispute, the wet oxidation technique is to be used.
