Abstract

Procedure of copper quantitative analysis in the fuel after its corrosion attack against structural materials has been developed to improve the methods of aviation fuel quality assessment. Preparation of fuel for the analysis is carried out by mineralization process. The fuel sample is dissolved in concentrated nitric acid in the presence of hydrogen peroxide until the water-fuel phase boundary is disappeared. Copper concentration is measured by atomic absorption spectrometry with the use of acetylene-air flame on the absorption of copper resonance analytical line (324.8 nm). On the basis of the developed procedure VIAM standard STO 1-595-7-461–2015 «Quantitative analysis of copper in the fuel» was published.
