摘要：

Two new methods for the determination of enrofloxacin in commercial formulations and canine urine samples, based on adsorptive stripping voltammetry (AdSV), are proposed. One of the proposed method uses univariate calibration to analyse enrofloxacin in commercial formulations and the other applies principal component regression (PCR) to the voltammetric measurements to determine enrofloxacin in the presence of its metabolite ciprofloxacin. The linear concentration ranges of application were 4-25 and 18-55 ng ml(-1) by using an accumulation potential of -0.3 V and a 180 or 60 s accumulation time, respectively for the univariate method. The first concentration range was used for the multivariate method. Both methods were successfully applied to the analysis of commercial formulations and spiked canine urine samples, respectively.
