摘要
A novel chemiluminescence (CL) method is developed for determination of ofloxacin and levofloxacin with Ag(III) complex in H(2)SO(4) solution medium. The CL intensity is proportional to drug concentration in a wider range with a correlation coefficient of 0.999. The limit of detection (s/n = 3) for ofloxacin and levofloxacin was 5.3 x 10(-9) g ml(-1) and 8.3 x 10(-9) g ml(-1), respectively, and their recoveries from urine and serum samples were in the range of 90.1-112% with the RSDs of 1.0-2.8%. The proposed method was applied for analysis of real samples with satisfactory result. The possible CL mechanism was discussed.
