Butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tert-butylhydroquinone (TBHQ) are synthetic antioxidants used in the food industry. Herein, we describe the development of a novel graphite nanocomposite-based electrochemical sensor for the multiplex detection and measurement of BHA, BHT, and TBHQ levels in complex food samples using a linear sweep voltammetry technique. Moreover, our newly established analytical method exhibited good sensitivity, limit of detection, limit of quantitation, and selectivity. The accuracy and reliability of analytical results were challenged by method validation and comparison with the results of the liquid chromatography method, where a linear correlation of more than 0.99 was achieved. The addition of sodium dodecyl sulfate as supporting additive further enhanced the LSV response (anodic peak current, I) of BHA and BHT by 2- and 20-times, respectively.
丁基羟基茴香醚（BHA）、丁基羟基甲苯（BHT）和叔丁基对苯二酚（TBHQ）是食品工业中使用的合成抗氧化剂。在此，我们描述了一种新型基于石墨纳米复合材料的电化学传感器的开发，该传感器可用于使用线性扫描伏安法技术对复杂食品样品中的 BHA、BHT 和 TBHQ 水平进行多重检测和测量。此外，我们新建立的分析方法表现出良好的灵敏度、检测限、定量限和选择性。通过方法验证和与液相色谱法结果的比较来挑战分析结果的准确性和可靠性，其中实现了超过 0.99 的线性相关性。添加十二烷基硫酸钠作为支持添加剂可分别将 BHA 和 BHT 的 LSV 响应（阳极峰电流，I）增强 2 倍和 20 倍。
