Wear Metal Analysis in Engine Oil by Microwave Digestion and Atomic Absorption Spectroscopy

reportActive / Technical Report | Accession Number: ADA223070 | Open PDF

Abstract:

Digestion procedures are described for the analysis of wear metals in National Bureau of Standards NBS oil samples by a closed vessel microwave digestion system. Samples were analyzed by flame atomic absorption spectroscopy. Recoveries of Al, Fe, Ni, Cu, and Pb in the 300-ppm NBS oil ranged from 98 to 103 with standard deviations from 3 to 14. This method serves as a relatively quick matrix destruction technique for the quantitation of metals in oil. Keywords Aluminum, Iron, Microwave digestion, Atomic absorption, Lead, Nickel, Copper, Metal analysis, Oil.
