Sorbent Materials for the Preconcentration of Platinum-Group Metals

Abstract

Sorption methods, including solid-phase extraction, are widely used in the determination of platinum-group metals (PGMs), which is confirmed by a permanently large number of publications. This review is devoted to the description of different types of sorbents developed for the preconcentration and selective recovery of PGMs and their use in the analysis of geological, natural, and technological samples. Trends in the design of materials and physical fields to intensify the processes of the solid-phase extraction of PGMs are discussed. The review considers publications mainly for 2010–2025.
