Summary

ISO 5398-4:2007 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.
