标准范围
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.
