| 中文摘要 | one of the most attractive features of derivative spectrometry is its higher resolving power. in the present power, numerical derivative techniques are evaluated from the viewpoint of increase in selectivity, the latter being expressed in terms of the interferent equivalent concentration (iec). typical spectral interferences are covered, including flat background, sloped background, simple curved background and various types of line overlap with different overlapping degrees, which were defined as the ratio of the net interfering signal at the analysis wavelength to the peak signal of the interfering line. the iecs in the derivative spectra are decreased by one to two order of magnitudes compared to those in the original spectra, and in the most cases, assume values below the conventional detection limits. the overlapping degree is the dominant factor that determines whether an analysis line can be resolved from an interfering line with the derivative techniques. generally, the second derivative technique is effective only for line overlap with an overlapping degree of less than 0.8. the effects of other factors such as line shape, data smoothing, step size and the intensity ratio of analyte to interferent on the performance of the derivative techniques are also discussed. all results are illustrated with practical examples. |
