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.
