Abstract:

Trivalent metallic ions(Cr3+, Fe3+ and Al3+) play important roles in environment and human health. It is exhausting using different sensor in different conditions for detection of all the trivalent metallic ions. Single probes for detecting all of these trivalent metallic cations simultaneously with high sensitivity and selectivity have attracted great attention. A novel rhodamine-based probe P was synthesized from rhodamine B. It is showed that probe P acts as a “turn on” fluorescent probe for trivalent metallic ions(Fe3+, Cr3+ and Al3+) recognition. Probe P is highly selective to trivalent metallic ions over other monovalent or divalent metallic ions in V(CH3OH):V(Tris-HCl)=9:1. Furthermore, probe P is highly sensitive to trivalent metallic ions. The detection limits of probe P for Cr3+, Al3+ and Fe3+ are 3.0×10-4, 2.7×10-4 and 1.0×10-4 mol/L, respectively. Probe P could be used in the detection of Cr3+, Al3+ and Fe3+.
