Determination of Rare Earth Elements in Aluminum by Inductively Coupled Plasma-Atomic Emission Spectroscopy

Abstract
Inductively coupled plasma-atomic emission spectroscopy is evaluated for the determination of 14 rare earth elements in aluminum. Spectral line interference, limit of detection, and background equivalent concentration values are evaluated, and quantitative recovery is obtained from aluminum samples spiked with rare earth elements. The procedure is simple and suitable for routine process control analysis.
