Minor and Trace Chemical Elements in Rubbers: Measurement Results on X-ray Fluorescence Spectrometer TIGER-S8-Bruker

Abstract

Industrial synthetic rubbers were studied using X-ray fluorescence spectroscopy: polyisoprene rubber SKI-3, butyl rubber BK-1675, polybutadiene rubber SKDN and SKD-L, ethylene-propylene-diene rubber SKEPT. The results of semi-quantitative (without preliminary quantitative calibration) determination of the content of more than 25 different chemical elements are considered. Using the TIGER-S8-Bruker wave-dispersive device as an example, the advantages and disadvantages of using X-ray fluorescence spectroscopy in the study of rubbers are demonstrated. It is shown that even with a semi-quantitative level of analysis, it is possible to assess the content of elements that affect the stability of rubbers, sanitary and environmental indicators, to identify the rubber being studied and the corresponding production technology.
