Development of the simultaneous analysis methods on the HR-CS-ET-AAS device and their use in environmental analysis
 Jurnečka, Roman ; Doležalová Weissmannová, Helena (referee) ; Komendová, Renata (advisor)
This thesis deals with the development of simultaneous determination methods using atomic absorption spectrometry with a continuous radiation source and high-resolution monochromator. The determination methods were developed especially with regard to the analysis of environmental matrices. Two methods of simultaneous determination were developed with the application of three types of environmental samples. The first of them was focused on the simultaneous determination of nickel and iron in tea leaves. This method was also applied to soil samples. The second method is the determination of manganese and iron in water. Here I also examined the influence of the modifier. Furthermore, the combination of wavelengths of the already established method of simultaneous determination of cadmium and iron in oat products was taken from the literature. As part of the thesis, this method was optimized to determine these specific elements in tea. The primary advantages of simultaneous analysis include the saving of chemicals, including argon, as well as less time-consuming operation. The developed methods can be put into practice. The output is a design of a laboratory task for the introduction of simultaneous analysis into teaching.
