本文件规定了通过碱性消解和离子色谱分光光度检测法测定固体废物和土壤中的Cr（VI）。该方法可用于测定大于0.1？mg/kg固体中的Cr（VI）-质量分数。 注？如果是还原或氧化废物基质，则无法报告有效的Cr（VI）含量。

This document specifies the determination of Cr(VI) in solid waste material and soil by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1？mg/kg. NOTE？In case of reducing or oxidising waste matrix no valid Cr(VI) content can be reported.
