Summary: | [Display omitted]
•An enhanced fluorescent chemosensor is introduced for detection of Lu3+ ion.•The probe exhibits high selectivity toward Lu3+ in comparison with common metal ions.•The limit of detection was obtained 8.6×10−7molL-1.
A turn-on fluorescent chemosensor is introduced for the detection of Lu3+ ion using N-[3-methyl]-2-[pyridine-2-amido] phenyl] pyridine-2-carboxamide (L) molecule. Fluorescent emission intensity of L enhances after binding to Lu3+ ions in ethanol–water solution (1:9, v/v). The observed enhancement is the result of a strong covalent binding between Lu3+ ion and L (the binding constant value is 2.0×106mol−1L). The proposed optical chemosensor can be applied for the analysis of Lu3+ ion in a linear range of 3.3×10−7 to 1.0×10−5molL−1. The limit of detection was obtained 8.6×10−7molL−1. The probe exhibits high selectivity toward Lu3+ ion in comparison with common metal ions. The proposed fluorescent chemosensor was successfully used in the determination of Lu3+ ion in some water samples. |
