标准范围
本文件描述了皮革水溶液中铬的测定方法。这是对皮革中总铬的分析;它不是特定于化合物或特定于其氧化状态。本方法描述了通过电感耦合等离子体(ICP)测定铬,适用于氧化铬含量超过1 mg/kg的皮革。包括两种制备待分析溶液的技术。如有争议,可使用湿式氧化技术。
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.
