Reaction of Imidazoline-2-Selone with Acids and Its Use for Selective Coordination of Platinum Ions on Silica Surface

Abstract

A new and efficient system for the selective recovery of platinum ions from conventional cheap transition metal mixtures was developed. We found that the selone is reactive toward the conventional acids. Mesoporous silica functionalized by reaction of selone showed excellent selectivity to platinum ions among various transition metal ions.
