摘　　要：本文构建一种基于羧基化多壁碳纳米管(MWCNTs-COOH)纳米材料的电化学传感器,并通过使用方波伏安法(SWV)实现了对食品中玉米赤霉烯酮(Zearalenone, ZEA)快速、灵敏的检测。在优化好的实验条件下,该传感器检测ZEA的线性范围为0.2~6μg·m L-1,检出限为0.067μg·m L-1。该方法具有较高的选择性,较好的重现性、重复性。并且实际样品加标回收率为98.4%~106.7%,表明该电化学传感器在实际应用中具有很大潜力。In this paper, an electrochemical sensor based on carboxylic multi-walled carbon nanotubes(MWCNTs-COOH) nanomaterial was constructed and used for the rapid and sensitive detection of ZEA via square wave voltammetry(SWV). Under optimized experimental conditions, the linear range of ZEA detection via the sensor is 0.2~6 μg·mL-1, with a low detection limit of 0.067 μg·m L-1. Besides, the method shows high selectivity, good reproducibility and repeatability. The recoveries in actual samples analysis are 98.4 %~106.7 %, which indicates that the electrochemical sensor has great potential in practical application.
