Recent Advances of Trace Analysis of Iron and Steel by Separation and Preconcentration Techniques

Abstract

Accurate chemical analysis of iron and steel for trace elements usually requires appropriate separation and preconcentration procedures prior to instrumental measurements of analytes. The present review is concerned exclusively with recent advances in separation and preconcentration techniques, including liquid-liquid extraction, ion exchange, solid-phase extraction, coprecipitation, volatilization and electrolysis.
