Abstract

In this study, a terbium(Ш) complex, Tb(SSA) 4 (SSA = sulfosalicylate), was synthesized and employed to detect toxic chromate anion (CrO 4 2− ) as a visually identifiable probe. Luminescence investigations confirmed that the Tb complex is an excellent probe with high selectivity, high sensitivity (I 0 /I 100 μM = 9.5), and a low detection limit (2.8 × 10 −8 M), targeting CrO 4 2− in aqueous solution. The simple fluorescence-based probe can be quickly and easily prepared, and enables the reliable, visual detection of CrO 4 2− ion in daily applications.
