Abstract

A novel fluorescein derivative furfuraldehyde fluorescein hydrazone (FFH) has been synthesized by reacting fluorescein hydrazide with furfuraldehyde and characterized by ¹H NMR, ¹³C NMR, MS and elemental analysis. Addition of Cu²⁺ to the solution of FFH results in a rapid color change from colorless to yellow together with an obvious new band appeared at 502 nm in the UV-vis absorption spectra. This change is attributed to the spirocycle form of FFH opened via coordination with Cu²⁺ in a 1:1 stoichiometry and their association constant is determined as 6.1 × 10⁴ L mol^-1. Experimental results indicate that the FFH can provide a rapid, selective and sensitive response to Cu²⁺ with a linear dynamic range 6.6-330 μmol/L. Common interferent ions do not show any interference on the Cu²⁺ determination. It is anticipated that FFH can be a good candidate probe and has potential application for Cu²⁺ determination in aqueous solution.
