The sulfur content in fuels, Diesel fuels, and in the solutions of dibutyls
ulfide in a white oil was determined by various methods. The results obtain
ed by elemental analysis have shown that the method is not advisable for th
e determination of sulfur in fuels. A good agreement was found by comparing
the results in the determination of the sulfur content by Grote-Krekeler's
and Bermann-Moritz's methods and by the energy-dispersive X-ray fluorescen
ce analysis. The last method is the modern, comfortable, and timesaving met
hod enabling the fast and precise determination of sulfur contents in the v
arious types of samples.
