QUANTITATIVE DETERMINATION OF BINARY AND TERNARY OF BIODIESEL/DIESEL, MINERAL OIL AND SOLVENT MIXTURE WITH CHEMOMETRIC APPROACH
Project no. 519 · Status: Kapanmış · 2018
Summary
In 2018, with the regulation introduced by the Energy Market Regulatory Authority, it has become obligatory to blend biodiesel at least 0.5 % (V / V) to diesel fuel. In addition, simulating standard fuel quality the use of biodiesel, mineral oil and solvent mixtures in the vehicles has led to counterfeiting of fuels. Because both structure of the fuels and the mineral oils are complex, simultaneous determinations of the mixtures are expensive and time consuming by known chromatographic methods. In contrast to chromatographic analyzes, combining chemometric techniques with faster, lesser sample spectroscopic techniques is advantageous for the analysis of complex mixtures. In this thesis, it was aimed to develop the method for the determination of the binary and ternary mixtures of diesel / biodiesel, mineral oil and solvent. The spectra of the prepared mixtures with Fourier Transform Infrared (FTIR) spectrometry were taken and the partial least squares method (PLS) was applied to the spectral data. The PLS method allows simultaneous analysis of biodiesel / diesel, mineral oil and solvent mixtures, based on calibration and validation results.
