Quality control
of drug fleroxacin dosage, its monitoring in biological fluids, and research of
drug’s metabolism and action are an important analytical task.
A new
chemiluminescence (CL) reaction system was established for the determination of
fleroxacin (FLX). The trivalence dysprosium-sensitized CL emission
mechanism was investigated by comparing the fluorescence emission with CL
spectra.
The CL spectra of
FLX-KMnO 4 -Na 2 S 2 O 3 -H 6 P 4 O 13 system are from the narrow
characteristic emission of Dy 3+ at 482 and 578 nm ( 4 F 9 → 6 H 15/2 , 4 F 9
→ 6 H 13/2 ) through the energy transfer from
the excited SO 2 * to analyte, followed by intramolecular energy transfer from
analyte* to Dy 3+ .
