Abstract

A simple chalcone based dual analyte fluorescent probe FPC for Al³⁺ and HSO₃^- ions was developed. FPC detects both the analytes through a "turn off-on" approach and by the PET and ICT mechanism. FPC showed high selectivity and sensitivity for Al³⁺ and HSO₃^- ions detection over other interfering and competing metal ions. In addition, the LOD of FPC for sensing Al³⁺ and HSO₃^- ions was found to be 1.60×10^-7M and 0.17×10^-6M respectively. An electrochemical desalination technique was employed for the complete removal of Al³⁺ ions from the environmental water samples by using the probe FPC.
