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 chrome by iodometric titration and is to be applicable to chromium-tanned leathers which are expected to have chromic oxide contents in excess of 0,3 %. Two different methods are described as alternatives for obtaining chromium in a suitable solution. It is appropriate to use either method.
