| 摘 要： | Tb^3＋能够增强Ce^4＋-H2SO3-沙拉沙星体系化学发光强度,据此建立了测定沙拉沙星的流动注射化学发光新方法,该法快速、简单、灵敏度高、选择性好。其线性范围为1.5×10^-8-5.0×10^-4g/mL,检出限为8.3×10^-9g/mL,相对标准偏差（n=11,c=2.5×10^-5g/mL）为2.2%。利用该法测定了盐酸沙拉沙星注射液中沙拉沙星的含量,回收率为95.1%-101.4%。

| Abstract: | Based on the chemiluminescence reaction of Ce^4 ＋-H2SO3-Sarafloxacin could be sensitized by Tb^3 ＋,a chemiluminescence method for the determination of Sarafloxacin injection was established by flowinjection. The result indicate that the method is simple,rapid,accurate and fit for the rapid determination of Sarafloxacin. The calibration curve was linear in the concentration range of 1. 5 × 10^- 8- 5. 0 × 10^- 4g / mL,the detection limit is 8. 3 × 10^- 9g / mL,the RSD is 2. 2%（ n = 11,c = 2. 5 × 10^- 5g / mL）. The mass recovery range was 95. 1% - 101. 4%. |
