| 中文摘要 | the performance of kalman filtering, synchronous excitation and numerical derivative techniques for the resolution of overlapping emission spectra in spectrofluorimetry was studied. the extent of spectrum overlap was quantitatively described by the separation degree d(s), defined as the ratio of the peak separation to the full width at half-maximum of the emission spectrum of the interferent. for the system of rhodamine b and rhodamine 6g with a large d(s) of about 0.4, both kalman filtering and synchronous techniques are able to resolve the overlapping spectra well and to give satisfactory results while the derivative spectra are still overlapped with each other. moreover, the sensitivities are greatly decreased in derivative techniques. for more closely spaced spectra emitted by the complexes of al and zn with 7-iodo-8-hydroxyquinoline-5-sulphonic acid (ferron)-hexadecyltrimethylammonium bromide, the synchronous excitation technique cannot completely separate the overlapping peaks, although it increases the separation degree from 0.25 in the conventional spectra to 0.37 in the synchronous spectra. on the other hand, kalman filtering is capable of resolving this system. when the al/zn intensity ratio at the central wavelength of al was > 1, however, the accuracy and precision of the estimates for zn concentration produced by the kalman filter became worse. in this event, the combination of synchronous excitation and kalman filtering can much improve the analytical results. |
