Selective removal and quantification of Cu(Ⅱ) using fluorescent iminocoumarin-functionalized magnetic nanosilica

摘要

A newly prepared iminocoumarin-functionalized magnetic nanosilica (Ni@ SiO_2-1) was found to form a selective stable complex with Cu~(2+) over other metal ions. Quantification of Cu~(2+) ions in aqueous solution using Ni@SiO_2-1 is demonstrated through a fluorescent demetallization ensemble process.
