本文根据 Tb3+能显著增强 Ce ( ) - SO2 - 3- NFLX体系的化学发光 ,建立了流动注射铽敏化化学发光测定诺氟沙星的新方法。本法的线性范围为 9.0× 1 0 - 9～ 1 .0× 1 0 - 6 mol/L,检出限为 4.5× 1 0 - 11mol/L。利用该法测定了诺氟沙星胶囊中诺氟沙星的含量 ,并对血清和尿样进行了回收率测定 ,回收率在 1 0 0 .4%～ 1 0 5 .7% ,结果令人满意。
In this paper, a new method for the determination of norfloxacin by flow injection of terbium sensitized chemiluminescence was established based on the fact that Tb3 + can significantly enhance the chemiluminescence of Ce () - SO2 - 3 - NFLX system. The linear range of this method is 9.0 × 10 ~ 9 ~ 1.0 × 10 6 mol / L with a detection limit of 4.5 × 10 11 mol / L. The method was used to determine the content of norfloxacin in norfloxacin capsules, and the recovery of serum and urine samples was determined. The recoveries ranged from 1.04% to 105.7% satisfaction.
