Abstract

This paper reports a flow‐injection chemiluminescence method for the determination of ofloxacin (OFLX) using the Ru(bpy)~2~(CIP)^2+^–Ce(IV) system. Under the optimum conditions, the relative CL intensity was proportional to the concentration of OFLX in the range 3.0 × 10^–8^–1.0 × 10^–5^ mol/L and the detection limit was 4.2 × 10^–9^ mol/L. The proposed method has been successfully applied to the determination of ofloxacin in pharmaceuticals and human urine. The chemiluminescence mechanism of the system is also discussed.

## Abstract A new flow injection chemiluminescence (CL) system was used for the determination of noscapine. This technique is based on the reduction effect of noscapine on the Ru(phen)~3~^3+^, which is produced by reaction between Ru(phen)~3~^2+^ and acidic Ce(IV) solutions, and this rapid reductio
