Summary: A potentiometric study was conducted on the interactions between l-carnosine (CAR) and the toxic metal cations Hg2+ and Cd2+. The study determined the formation constants of the metal (M2+)-CAR complex species in aqueous solution and investigated the influence of ionic strength and temperature on these constants. The sequestering ability of CAR towards Hg2+ and Cd2+ was compared with that towards Pb2+. Additionally, a more electroactive derivative called ferrocenyl-carnosine (FcCAR) was synthesized and evaluated for its complexing ability and sensing properties towards Hg2+ and Pb2+ using UV-vis spectroscopy and electrochemical techniques.
