摘要:

建立一种快速测定恩诺沙星的新方法。利用鲁米诺- 铁氰化钾化学发光体系,结合流动注射技术,对恩诺沙星进行测定。实验结果表明,恩诺沙星对鲁米诺- 铁氰化钾化学发光反应具有显著的增敏作用,在最佳实验条件下,该方法的线性范围为6 × 10-11~6 × 10-7mol/L,检出限(3σ)为2.7 × 10-13mol/L,RSD 为1.2%(n=11)。该方法用于注射液中恩诺沙星含量的测定,结果令人满意。

Abstract:

In order to establish a method for rapid determination of enrofloxacin, flow-injection chemiluminescence (FI-CL) system of luminol and potassium ferricyanide was developed. Results indicated that enrofloxacin exhibited a significantly enhanced effect on chemiluminescence reaction between luminol and potassium ferricyanide. An excellent linear range for enrofloxacin determination was 6 × 10-11-6 × 10-7 mol/L under the optimal condition. The detection limit of enrofloxacin was 2.7 × 10-13 mol/L and relative standard deviation for the determination was 1.2% (n = 11). A satisfactory analytical result was obtained during enrofloxacin determination using this developed method.

Key words: enrofloxacin, flow-injection chemiluminescence, luminol, potassium ferricyanide
