摘要
本文探讨了用国家标准方法《GB/T 7467-1987》测定水中六价铬时,几种典型的还原性物质在不同浓度下对测定结果的影响;同时考察了不同的抗干扰方法测定时,这几种还原性物质在不同浓度下对测定结果的影响.
Abstract
This paper discusses the influence of several typical reducing substances on the determination results of hexavalent chromium in water at different concentrations when the national standard method GB/T 7467-1987 is used.Simultaneously the effects of these reducing substances at different concentrations on the measurement results are examined when using different anti-interference methods.
