Leather. Chemical determination of chromic oxide content - Quantification by atomic absorption spectrometry subscription-only ISO 2597-2 specifies two titrimetric1 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 chromium by atomic absorption spectrometry and is applicable to leathers which are expected to have chromic oxide contents in excess of 5 mg kg. Two techniques for the preparation
