Cyromazine is an insect growth regulator insecticide with high selectivity and is widely used in the production and cultivation of fruits and vegetables. In recent years, incidents of excessive cyromazine residues in food have occurred frequently, and it is urgent to establish an accurate, fast, and convenient method for the detection of cyromazine residues to ensure the safety of edible agricultural products. To achieve rapid detection of cyromazine residues, we prepared a molecularly imprinted electrochemical sensor for the detection of cyromazine residues in agricultural products. Samples of tomato ( Miller), cowpea (), and water were tested for the recovery rate of cyromazine. The results showed that the concentration of cyromazine showed a good linear relationship with the peak response current of the sensor developed in this study. The lower limit of detection for cyromazine was 0.5 µmol/L, and the sensor also had good reproducibility and interference resistance. This paper can be used as a basis for the study of methods for the detection of cyromazine residues in edible agricultural products.
环丙氨嗪是一种具有高选择性的昆虫生长调节剂杀虫剂，广泛应用于水果和蔬菜的生产和种植中。近年来，食品中环丙氨嗪残留超标事件时有发生，迫切需要建立一种准确、快速、方便的环丙氨嗪残留检测方法，以确保食用农产品的安全。为了实现环丙氨嗪残留的快速检测，我们制备了一种用于检测农产品中环丙氨嗪残留的分子印迹电化学传感器。对番茄（Miller）、豇豆（）和水的样品进行了环丙氨嗪的回收率测试。结果表明，所研制的传感器的峰响应电流与环丙氨嗪的浓度呈良好的线性关系。环丙氨嗪的检出限为 0.5µmol/L，该传感器还具有良好的重现性和抗干扰性。本文可为食用农产品中环丙氨嗪残留检测方法的研究提供依据。
