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

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.
