Leather. Chemical determination of chromic oxide content - Quantification by titration algolia-search-ignore copper or aluminum1 Scope 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 %.
