  • Europium based metal organic framework for palladium sensing
    Patent number: 11124529
    Abstract: A method of detecting Pd2+ in an aqueous solution is described. The method involves mixing an Eu-based metal organic framework with the aqueous solution and measuring the amount of fluorescence quenching. The fluorescence quenching is specific to Pd2+ and also allows a 44 ppb detection limit of Pd2+. The Eu-based metal organic framework may be treated with a metal chelator and reused for sensitive detection of Pd2+.
    Type: Grant
