标准范围
This part of ISO 5398 describes a method for the determination of chromium in aqueous solution obtainedfrom leather. This is an analysis for total chromium in leather; it is not compound specific or specific to itsoxidation state.This method describes the determination of chrome by iodometric titration and is to be applicable tochromium-tanned leathers which are expected to have chromic oxide contents in excess of 0,3 %.
