Abstract
Abstract Commercially available 9-bromophenanthrene (9-BrP) was used as fluorescence probe for determination of trace palladium (Pd). Under the catalysis of Pd 2+ , 9-BrP is converted to phenanthrene, which can emit stronger fluorescence. Consequently, fluorescence of Pd sample is greatly enhanced, and the enhancement is positively correlated with the concentration of Pd 2+ . The catalytic reaction exhibits excellent selectivity and specificity, which enables a simplification on the pre-treatment of real sample. The method has a wide linear range of 0.07–18 μM and a detection limit of 50 nM for Pd 2+ . Detection and recovery experiments of Pd in lake water, Pd-carbon catalyzer and surface soil are also satisfactory, indicating that the method has better feasibility and application potential in routine determination of Pd.
