Major and Minor Constituents of Aluminum Alloys
Abstract
An accurate analysis of aluminum alloys is required for quality control and characterization purposes. The two analytical techniques atomic absorption spectroscopy and inductively coupled plasma atomic emission spectroscopy are used for the determination of major magnesium, lithium, copper, zinc, titanium, silicon (Mg, Li, Cu, Zn, Ti, Si) and minor trace (Be, Zr, Fe, Pb, Co, Ni, Cr, Mn, etc.) constituents of various aluminum alloys. Results obtained by the JCP-AES method are similar to that obtained by the AAS method for most of the elements. It was found that the analysis for Beryllium, Zirconium Titanium, and Silicon was more efficient and sensitive by the ICP-AES method whereas poor reproducibility was obtained for lithium. This method allowed the determination of major and minor constituents in the same solution without dilution. Comparative data is presented for standards and sample alloys obtained by both techniques. Keywords: Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma Atomic Emission Spectroscopy(ICP-AES).
