Abstract
In this article, the results of the study of the matrix effect in the determination of metals calcium, chromium, iron, nickel, copper, zinc, molybdenum, cadmium, barium and lead in base oil using Energy Dispersive X-Ray Fluorescence (EDX) are presented. Sensitivities obtained for each calibration curve were evaluated where calcium, chromium, copper, cadmium, barium and lead had the lowest sensitivities. In the case of cadmium, this parameter was lagging and the studies were not carried forward. The curves of the other metals in different base oils were evaluated for linearity. The elements chromium, copper, molybdenum and lead showed linearity problems in some cases. Therefore, curves in different base oils showed distinct mathematical behavior where the matrix effect was confirmed. The other curves were evaluated and existence of the matrix effect attributed to interference of C / H ratio was confirmed in the quantification of all elements. Metals iron, nickel and zinc exhibited the highest sensitivity and determination coefficients, showing that the method has application potential.
