Abstrakt: | A new fluorescence chemosensor based on ( Z )-2-(1-(3-oxo-3 H -benzo[ f ]chromen-2-yl)ethylidene)hydrazine-1-carbothioamide (CEHC) has been developed for the determination of Fe(iii) in drinking water. The optimum conditions were acetate buffer solution with a pH 5.0. In this approach, the determination of Fe(iii) is based on static quenching of the luminescence of the probe upon increasing concentrations of Fe(iii). The CEHC sensor binds Fe(iii) in a 1 : 1 stoichiometry with a binding constant K Competing Interests: The authors declare that they have no conflict of interest.
