Abstract

A newly prepared iminocoumarin-functionalized magnetic nanosilica (Ni@SiO2-1) was found to form a selective stable complex with Cu2+ over other metal ions. Quantification of Cu2+ ions in aqueous solution using Ni@SiO2-1 is demonstrated through a fluorescent demetallization ensemble process.
