Abstract

The simple yet efficient method for the detection of Cu²⁺ and Fe³⁺ by respective coordination of triazole-triazole and triazole-carbonate in aqueous media was achieved using the BisTriazole-Rhodamine B (BTRB) chemosensor. The addition of Cu²⁺ enhances the fluorescence intensity to 20 fold (Φ_f=0.31) while Fe³⁺ enhances 14 fold (Φ_f=0.12) in comparison with BTRB. Competitive experiments with BTRB-Cu²⁺ revealed that addition of Fe³⁺ displaces Cu²⁺ causes obvious fluorescence enhancement (2.8 fold). Application of BTRB probe was exploited by conducting a copper catalyzed model reaction from which total copper content in the catalytic product as an impurity was determined as 356 ppm.
