Flow-injection chemiluminescent determination of cefprozil using Tris (2,2′-bipyridyl) ruthenium (II)-permanganate system

The correlation coefficient was 0.9998 (n = 6) with a relative standard deviation (%R.S.D.) of 1.63% for 2.0 μg ml−1. The proposed method was successfully applied to commercial tablets. The average percentage recovery (n = 6) was 99.9 ± 1.40.
