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