Abstract

In this study, gold nanoparticles (AuNPs) were synthesized using sodium borohydride (NaBH 4 ) as reductant. AuNPs size and shape were experimented by using various characterization techniques. The synthesized AuNPs performance capability for atrazine (ATR) detection, at a glassy carbon electrode (GCE), was verified using cyclic voltammetry (CV) as the determining mode. AuNPs impressive electrochemical performance and stability at the GCE led to further studies, without the need to apply nafion. ATR linear concentration plot ranged from 10 to 17 nM, with a lower limit of detection (LOD) of 0.17 nM, and a regression coefficient (R 2 ) of 0.9934, under optimized conditions. The proposed sensor was very reliable, with a relative standard deviation (RSD) of 1.1%, for n = 20, and it was quite sensitive for ATR, with no discernible interference from other ions. Consequently, AuNPs were effectively used to identify ATR in several pesticide industry wastewater samples.

纳米金修饰玻碳电极伏安法测定农药废水中的阿特拉津

本研究以硼氢化钠(NaBH 4)为还原剂合成了金纳米颗粒(AuNPs)。利用各种表征技术对AuNPs的大小和形状进行了实验。采用循环伏安法(CV)对合成的AuNPs在玻碳电极(GCE)上检测阿特拉津(ATR)的性能进行了验证。在GCE上，unps令人印象深刻的电化学性能和稳定性导致了进一步的研究，而无需应用国家。在优化条件下，ATR线性浓度图范围为10 ~ 17 nM，检测下限(LOD)为0.17 nM，回归系数(r2)为0.9934。该传感器非常可靠，当n = 20时，相对标准偏差(RSD)为1.1%，并且对ATR非常敏感，不受其他离子的干扰。因此，利用AuNPs有效地识别了几种农药工业废水样品中的ATR。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
