A novel rhodamine-based probe L was synthesized and characterized. The results showed that probe L acted as a fluorescent enhancement probe for Cr3+, Fe3+ and Al3+ recognition in CH3OH/H2O (V:V=8:2, c(Tris)=10 mmol/L, pH=7.2). L is highly selective to trivalent ions Cr3+, Fe3+ and Al3+ over other monovalent or divalent ions. Detection limits of probe L for Cr3+, Fe3+ and Al3+ are 2.1×10-4, 2.3×10-4 and 4.4×10-4 mol/L, respectively, which make it have potentially application value in Cr3+, Fe3+ and Al3+ detection in various water samples.

Key words: rhodamine, trivalent ions, fluorescence enhancement
