摘要

目的:食品取证是一个新兴领域,本综述的第一部分展示了最常用偶氮染料的毒性作用和用于检测的仪器方法。电化学检测具有很多优势,因此本综述讨论了电化学检测中使用的最重要技术的意义。本综述的主要部分强调了表面修饰电极,用于检测最重要的偶氮染料,以实现低检测限(LOD):方法:利用 scopus、science direct 和其他科学数据库,使用有毒偶氮染料、电化学检测、改性电极、LOD 等特定关键词进行了全面的文献研究。结果:从已发表的文献中可以看出,随着人们对电化学技术领域的兴趣日益浓厚,人们对工作电极的改性给予了高度重视。结果明确显示,改性电极的性能优于裸电极,且 LOD 值更低:根据文献报告可以得出结论,与其他检测方法相比,电化学技术具有更高的可靠性和可重复性。对电极材料进行适当改性是影响灵敏度的主要因素。电化学传感器可以设计得更灵敏、更可靠、更便宜。毒理学家可以有效地利用这些传感器来检测食品样本中的痕量有害染料。

Recent advances in electrochemical detection of common azo dyes.

Recent advances in electrochemical detection of common azo dyes.

Purpose: Food forensics is an emerging field and the initial part of this review showcases the toxic effects and the instrumental methods applied for the detection of the most commonly used azo dyes. Electrochemical detection has a lot of advantages and hence the significance of the most important techniques used in the electrochemical detection is discussed. The major part of this review highlights the surface modified electrodes, utilized for the detection of the most important azo dyes to achieve low detection limit (LOD).

Methods: A thorough literature study was conducted using scopus, science direct and other scientific databases using specific keywords such as toxic azo dyes, electrochemical detection, modified electrodes, LOD etc. The recent references in this field have been included.

Results: From the published literature, it is observed that with the growing interests in the field of electrochemical techniques, a lot of importance have been given in the area of modifying the working electrodes. The results unambiguously show that the modified electrodes outperform bare electrodes and offer a lower LOD value.

Conclusion: According to the literature reports it can be concluded that, compared to other detection methods, electrochemical techniques are much dependable and reproducible. The fabrication of the electrode material with the appropriate modifications is the main factor that influences the sensitivity. Electrochemical sensors can be designed to be more sensitive, more reliable, and less expensive. These sensors can be effectively used by toxicologists to detect trace amounts of harmful dyes in food samples.

期刊介绍: The journal Forensic Toxicology provides an international forum for publication of studies on toxic substances, drugs of abuse, doping agents, chemical warfare agents, and their metabolisms and analyses, which are related to laws and ethics. It includes original articles, reviews, mini-reviews, short communications, and case reports. Although a major focus of the journal is on the development or improvement of analytical methods for the above-mentioned chemicals in human matrices, appropriate studies with animal experiments are also published. Forensic Toxicology is the official publication of the Japanese Association of Forensic Toxicology (JAFT) and is the continuation of the Japanese Journal of Forensic Toxicology (ISSN 0915-9606).
