Colorimetric determination of iron (III) with 1,10-phenanthroline

Cu2+ chemosensing behaviour of self-organized micro-array structures of a donor–acceptor bichromophoric compound anchored onto Ag nanoisland films

“…However, Fe(III) is significantly soluble in water only for very low pH values. Moreover, when needed, such ionic species can be easily detected by complementary colorimetric methods [19,20].…”
