It is necessary to determine whether synthetic dyes are present in food since their excessive use has detrimental effects on human health. For the simultaneous assessment of tartrazine and Patent Blue V, a novel electrochemical sensing platform was developed. As a result, two artificial azo colorants (Tartrazine and Patent Blue V) with toxic azo groups (-NN-) and other carcinogenic aromatic ring structures were examined. With a low limit of detection of 0.06 μM, a broad linear concentration range 0.09μM to 950μM, and a respectable recovery, scanning electron microscopy (SEM) was able to reveal the excellent sensing performance of the suggested electrode for patent blue V. The electrochemical performance of an electrode can be characterized using cyclic and differential pulse voltammetry, and electrochemical impedance spectroscopy. Moreover, the classification model was created by applying binary classification assessment using enhanced artificial intelligence comprises of support vector machine (SVM) and Genetic Algorithm (GA), respectively, a support vector machine and a genetic algorithm, which was then validated using the 50 dyes test set. The best binary logistic regression model has an accuracy of 83.2% and 81.1%, respectively, while the best SVM model has an accuracy of 90.3% for the training group of samples and 81.1% for the test group (RMSE = 0.644, R2 = 0.873, C = 205.41, and = 5.992). According to the findings, Cu-BTC MOF (copper (II)-benzene-1,3,5-tricarboxylate) has a crystal structure and is tightly packed with hierarchically porous nanomaterials, with each particle's edge measuring between 20 and 37 nm. The suggested electrochemical sensor's analytical performance is suitable for foods like jellies, condiments, soft drinks and candies.
有必要确定食品中是否存在合成染料,因为它们的过度使用会对人体健康造成有害影响。为了同时评估食用柠檬黄和专利蓝 V,开发了一种新型电化学传感平台。结果,对两种具有毒性偶氮基团(-NN-)和其他致癌芳环结构的人工偶氮着色剂(食用柠檬黄和专利蓝 V)进行了检查。所提出的电极对专利蓝 V 具有出色的传感性能,其检测限低至 0.06 μM,线性浓度范围为 0.09μM 至 950μM,回收率高。扫描电子显微镜 (SEM) 能够揭示建议的电极对专利蓝 V 的出色传感性能。可以使用循环伏安法和差分脉冲伏安法以及电化学阻抗谱来描述电极的电化学性能。此外,使用支持向量机 (SVM) 和遗传算法 (GA) 分别对增强的人工智能分类模型进行了二元分类评估,然后使用 50 种染料测试集对其进行了验证。最佳二元逻辑回归模型对训练组样本的准确率为 83.2%,对测试组样本的准确率为 81.1%,最佳 SVM 模型对训练组样本的准确率为 90.3%,对测试组样本的准确率为 81.1%(RMSE = 0.644,R2 = 0.873,C = 205.41,= 5.992)。根据研究结果,Cu-BTC MOF(铜(II)-苯-1,3,5-三甲酸酯)具有晶体结构,且由紧密堆积的分级多孔纳米材料组成,每个颗粒的边缘尺寸在 20 到 37nm 之间。所提出的电化学传感器的分析性能适用于果冻、调味料、软饮料和糖果等食品。
