Abstract

In this work a new model of carbon paste electrode was employed to determine sulfamethoxazole (SMX), an antibiotic used to treat infections in human and veterinary medicine, by the square wave voltammetric modality (SWV). More specifically, the electrochemical behavior of SMX was investigated by cyclic voltammetry (CV), and the quantitative analysis of SMX was provided by SWV. The analytical curve was obtained with a linear correlation coefficient (r) of 0.985 and standard deviation (SD) of 0.005 mu A. Limits of detection and quantification were found as 2.3x10(-6) and 7.7x10(-6) mol L-1, respectively. According to the obtained results, the new carbon paste prototype electrode can successfully be employed in this kind of electroanalytical applications. (AU)
