Реферат

Automobile catalysts have recently appeared on Russian market as a source of secondary precious metals. That's why, the analytical control sphere found the necessity of development of high-accuracy methods of definition of their platinum metal content. Various methods of chemical sample preparation of metal-based dead automobile catalysts were studied, and advantages and disadvantages of existing methods of sample transfer into the solution were found. The optimal method of chemical sample preparation chose the sample decomposition in analytical autoclaves in the mixture H2O2 – HCl with preliminary sorption release of platinum, palladium and rhodium. It is necessary because of the spectral influences of matrix elements. The absence of significant divergences in results, obtained during the sample analysis by various methods, confirms the correct results of the analysis of platinum, palladium and rhodium finding using the autoclave chemical sample preparation and sorption. According to the research results, there was designed the method of platinum, palladium and rhodium finding in dead automobile catalysis on metallic basis by atomic-emission spectrometry with induction-connected plasma.
This work was carried out with the co-financing of the Ministry of Education and Science of the Russian Federation according to the program of increasing of competitiveness of National University of Science and Technology “MISiS” among the leading scientific-educational centers in the world for 2013–2020 and with the support of the Russian Scientific Funds (project No. 14-13-00897) and Russian Foundation for Basic Research (grant No. 13-03-00440).
