溶液干渣法已广泛用于化学光谱法中分析杂质含量。但用于分析环境样品时,光谱谱线强度受基体组成的影响很大,要得到准确的分析结果,必须使标准和分析样品组成相似。对组成变化大,复杂的环境样品,分析很困难。对一些贵重或难提纯的样品,配标准也不容易。多年来不少文献提到建立通用光谱定量分析法。其中比较重要的有Harvey 法,Addink法,Gordon法。这些方法使用公共基体,
Solution dry residue method has been widely used in chemical analysis of impurities in the spectrum. However, when used to analyze environmental samples, the spectral line intensity is strongly influenced by the composition of the matrix. To obtain accurate analytical results, the composition of the standard and analytical samples must be similar. Analysis of large and complex environmental samples is difficult. For some expensive or difficult to purify the sample, with the standard is not easy. Over the years a lot of literature mentioned the establishment of universal spectral quantitative analysis. Among the more important are the Harvey method, Addink method, Gordon method. These methods use a common substrate,
