Selection Of

A method is proposed for the determination of titanium and zirconium by inductively coupled plasma atomic emission spectrometry in aluminum alloys. Analytical lines of titanium and zirconium free from other elements significant spectral overlaps are selected. The selection of the sample preparation method was carried out, namely – dissolution in concentrated nitric acid. Studies of the metrological characteristics of the technique were carried out: for titanium and zirconium contents from 0.05 to 0.3 % of the mass. the accuracy index is no more than 5 % rel., which fully ensures the possibility of analytical control of the content of titanium and zirconium in products from aluminum alloys.

This article discusses the features of the determination of elements in uranium ores of the Shusarysu uranium-ore province by inductively coupled plasma atomic emission spectrometry in comparison with the ore standard of Ore Research & Exploration (Australia). A multi-stage method of sample preparation for measurement is considered. The existing and developed methods for determining the elemental composition of uranium ores are focused, as a rule, on the determination of specific elements using regulated analysis procedures. However, during routine analysis, we need to quickly and efficiently determine a larger list of elements available with one instrumental method. Various methods are used to obtain multielement analysis, among which mass spectrometry and inductively coupled plasma atomic emission analysis are most popular due to their high performance and low detection limits. The listed methods work with solutions, therefore, it is necessary to pay great attention to sample preparation and instrument calibration. The invention relates to a method for preparing samples for the study of materials by determining their chemical properties in a liquid state, for example, using inductively coupled plasma spectrometry. The method for preparing silicate and carbonate rock samples for spectrometric analysis includes autoclave decomposition of samples in a mixture of concentrated acids in a microwave oven at temperature and pressure and cooling the samples. Then carry out the introduction of the internal standard and bringing to the standard volume.

Introduction. The article is devoted to the relevance of choosing sample preparation method for heavy metals concentration determination in biological sample by using atomic emission spectrometry. Much attention is given to compare 2 methods of sample preparation: solid-phase extraction and microwave decomposition. As the result of analysis of heavy metals Fe, Zn, Rb, Cu, Ni, Al, Mn content using these sample preparation methods the following conclusions are drawn: maximum extraction of heavy metals is achieved by using microwave decomposition method.Aim. The purpose of this work was to compare the methods and conditions for the sample preparation of biological samples for the determination of the content of heavy metals using atomic emission spectrometry.Materials and methods. The object of the study to determine the content of heavy metals (Zn, Rb, Cu, Ni, Al, Mn) was the liver of golden hamsters of both sexes weighing 60–145 g of the type Golden Syrian SPF category, obtained from the Federal Research Center Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (Novosibirsk). Quantitative determination of heavy metals in biological samples was carried out on an Agilent 4100 atomic emission spectrometer with a microwave plasma (Agilent Technologies, USA).Results and discussion. Comparison of the content of elements in the sample using the sample preparations under study showed that the maximum extraction of heavy metals from biological samples is achieved when using the method of microwave decomposition. The most complete extraction of heavy metals from biological samples is achieved by extraction within 30 minutes.Conclusion. This method warrants the maximum metal extraction, is more accurate, rapid and less labor intensive compared to other methods considered, and is suitable for determining most heavy metals.
