Abstract

This study investigates the effects of boron concentration on boron-doped diamond (BDD) electrodes for electrochemical sensors of ciprofloxacin. The effects of boron concentration, scan rate, and pH of BDD electrodes with boron concentrations of 0.1, 0.5, and 1% were examined to determine the optimal conditions. Furthermore, square wave voltammetry (SWV) in phosphate buffer pH 7 was used to analyze the electrochemical behavior of ciprofloxacin. The results revealed a linear calibration curve in the concentration range of 30–100 μM with a recovery of 85–110%. Meanwhile, BDD electrode with the highest boron concentration in this experiment (1%) showed a very low limit of detection of 0.17 μM, meaning that 1% BDD gave a highly sensitive and significant measurement result for the electrochemical sensor of ciprofloxacin. With the results given, this study provides new insights for controlling boron concentrations in diamond electrodes for the electrochemical sensors of quinolone antibiotics.

金刚石电极中硼浓度对环丙沙星电化学传感器应用的影响

研究了硼浓度对环丙沙星电化学传感器掺杂硼金刚石(BDD)电极的影响。在硼浓度为0.1、0.5和1%时，考察硼浓度、扫描速率和pH对BDD电极的影响，确定最佳条件。采用方波伏安法(SWV)在pH为7的磷酸盐缓冲液中分析了环丙沙星的电化学行为。结果表明，在30 ~ 100 μM的浓度范围内具有良好的线性曲线，回收率为85 ~ 110%。同时，本实验中硼浓度最高的BDD电极(1%)的检出限极低，仅为0.17 μM，说明1%的BDD对环丙沙星电化学传感器的测量结果具有很高的灵敏度和显著性。本研究为喹诺酮类抗生素电化学传感器金刚石电极中硼的浓度控制提供了新的思路。
