固体废物六价铬分析样品碱消解快速前处理方法

AN METHOD OF ALKALI-DIGESTION RAPID PRE-TREATMENT OF HEXAVALENT CHROMIUM ANALYSIS SAMPLE IN SOLID WASTE

提出一种固体废物六价铬分析样品快速前处理方法,其消解条件、样品分析与现行国家标准方法相同,不同的是,样品消解后,用离心方法替代过滤方法,能实现样品的快速、准确分析。

This article presents an method of alkali-digestion rapid pre-treatment of hexavalent chromium analysis sample in solid waste,its digestion conditions and sample analysis method are the same as those of the current national standard method,the difference is that using centrifugal method instead of filtering methods after digestion,which can achieve quick and accurate analysis of samples.
