A new spectrofluorometric method was developed for the determination of trace amounts of heparin (Hep). Using ciprofloxacin (CIP)-terbium (Tb 3+ ) as a fluorescent probe, in a buffer solution of pH 7.20, Hep can remarkably enhance the fluorescence intensity of the CIP-Tb 3+ complex at λ = 545 nm; also, the enhanced fluorescence intensity the Tb 3+ ion is proportional to the concentration of Hep. The optimum conditions for the determination of Hep were also investigated. The dynamic range fordoi:10.2116/analsci.21.1207 pmid:16270580 fatcat:d5preu7perfzrn456dtvu4xdi4
