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

EN ISO 5398-4-2019 发布历史

This document 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 (ICP) 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 event of dispute@ the wet oxidation technique is intended to be used.
