标准摘要
[中文适用范围]： 该文件描述了一种测定皮革水溶液中铬的方法。 这是对皮革中总铬的分析；它不是特定的化合物或特定于其氧化态的化合物。 该方法描述了通过电感耦合等离子体 (ICP) 测定铬的方法，适用于氧化铬含量预计超过 1 mg/kg 的皮革。 其中包括两种制备待分析溶液的技术。 如有争议，应使用湿式氧化技术。 [外文原描述]： 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.
