Studying optical characteristics of aviation fuels samples stored under various conditions

Abstract

In this work the SPR method has been investigated. And it has been shown that this SPR method is the simple and reliable approach to study the quality of aviation kerosenes. The device "Plasmon-71" developed at the V. Lashkaryov Institute of Semiconductor Physics, NAS of Ukraine, with account of measured values of refraction index, has enabled to reveal changes in the kerosene composition after storing and applying it under conditions of aviation enterprise. The results of SPR measurements have been confirmed using infrared spectrometry, which allows revealing the presence of iron-, molybdenum-and chromium-containing organic compounds.
