Leather -- Chemical determination of chromic oxide content -- Part 4: Quantification by inductively coupled plasma - optical emission spectrometer (ICP-OES)

This standard has been reviewed* and then confirmed in 2011.

*ISO standards are reviewed every five years.

Abstract

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.
