Abstract: Pyrocatechol-1-aldehyde 2-pyridylhydrazone was synthesised and its ionisation constants spectrophotometrically determined. A procedure was developed for the spectrofluorimetric determination of 12–250 ng ml–1 of zinc in 50%V/V ethanol-water medium, acetate-buffered to apparent pH 5.5 (λex.= 398 nm, λem.= 521 nm), using the above reagent. Interferences were evaluated and the procedure was applied satisfactorily to the determination of zinc in potable tap water.
