Abstract
A "turn on" fluorescent probe based on denatured bovine serum albumin (BSA)-Pyronin Y complex (PYdBSA) has been prepared using a one pot approach. This probe can detect nanomolar concentrations of common contaminant ions (Hg2+, Cd2+, Cu2+, and Pb2+) found in wastewater. The probe shows the highest fluorescence response for Hg2+ (relative intensity set to 100%) and a very good response for Cd2+ (60%), Cu2+ (50%), and Pb2+ (20%). The probe is water-soluble and has photo excitation in the visible region (530 nm). More interestingly, the presence of the contaminant ions under consideration can be visually detected due to the distinct color formation upon addition of the analytes in micromolar (1 μM) concentrations. The limit of detection (LOD) with fluorometry is 9 nM for Hg2+ (
