基于四丁基四氟硼酸铵修饰的导电炭黑开发头孢羟氨苄抗生素电化学传感器
Development of Electrochemical Sensor for Cefadroxil Antibiotic Based on Conductive Carbon Black Decorated with Tetrabutylammonium Tetrafluoroborate
摘要
Abstract
The development of analytical methods for antibiotic detection has become crucial for public health.In this research,a novel and simple electrochemical sensor for sensitive detection of cefadroxil(CFL)antibiotic was developed.The glassy carbon electrode(GCE)was coated with cheap conductive carbon black VXC-72R that was decorated with tetrabutylammonium tetrafluoroborate(TBABF4),to construct the electrochemical sensor TBABF4/VXC-72R/GCE.It was found that CFL exhibited a reduction peak at approximately 0.22 V on TBABF4/VXC-72R/GCE.TBABF4/VXC-72R/GCE showed a linear response to CFL in a concentration range of 0.3-10.0 μmol/L,with a detection limit of 0.2 μmol/L(a signal-to-noise ratio of 3).TBABF4/VXC-72R/GCE showed good reproducibility,high storage stability and anti-interference performance.Analytical applications for CFL detection in real lake water,pharmaceutical tablet and fetal bovine serum samples were achieved.关键词
