Electrochemical behavior and determination od sulfaquinoxaline at glassy carbon electrode
Апстракт
Electrochemical behavior of sulfaquinoxaline (SQN) was investigated using cyclic (CV) and differential pulse voltammetry (DPV) at glassy carbon electrode (GCE). CV was applied to investigate the effect of the supporting electrolyte pH on the SQN electrochemical behavior. In the pH range 2.0 – 10.0, the best current response was obtained at pH 7.0 in phosphate buffer. Results indicated that SQN is oxidized in irreversible process. DPV method was optimized, and the linear dependence of peak current vs. SQN concentration was obtained in the range 3×10-6 ‒ 5×10-5 molL-1, with limits of detection and quantification of 1.53×10-6 molL-1 and 5.10×10-6 molL-1, respectively. DPV was successively applied for SQN determination in veterinary medicine NEOCOCCYN WSP, which contains amprolium hydrochloride, as active component too.
