一、前言光谱定量分析是通过未知试样和标准试样(已知试样)中待测元素谱线对的相对强度的比较分析来实现的。所以光谱分析对于标准试样的要求比较严格;而实际工作中常常很难得到满意的标准试样。想办法摆脱对标准试样的依赖,这是光谱分析工作者的努力方向。我们常看到的不依赖标准试样的光谱分析法系利用原分析试样中渗入已知量的待测元素的“增量法”。早在1941年,加脱拉(A.Gatterer)把溶液试样中加入已知量的待测元素,摄谱后制出初步标准曲线,利
I. INTRODUCTION Spectral quantitative analysis is achieved through a comparative analysis of the relative intensities of pairs of elements to be measured in unknown and standard samples (known samples). Therefore, the spectral analysis of the standard sample more stringent requirements; the actual work is often difficult to get a satisfactory standard sample. Try to get rid of the dependence on the standard sample, which is the direction of the spectral analysis efforts. We often see that does not rely on the standard spectral analysis of the sample system using the original analysis of the sample into the known amount of the test element “incremental method.” As early as 1941, A. Gatterer added a known amount of the analyte to the solution sample to produce a preliminary calibration curve
