Abstract

In the present study, a selective electrochemical technique to determine Zineb fungicide based on molecularly imprinted polymer (MIP) as a simple and fast method was developed. The MIP was synthesized on a glassy carbon electrode (GCE) modified with single walled carbon nanotube (SWCNT) through electropolymerization of ortho-aminophenol (o-AP) monomer and Zineb fungicide analyte. Some ions and compounds were examined as the interfering species to investigate the selectivity of the developed sensor. This research proposes simple determination of Zineb fungicide with a linear range 5–1000 fM and limit of detection (LOD) 1.6 fM. Finally, this strategy was successfully used to detect Zineb in some vegetable and fruit samples such as cucumber, potato, tomato, lettuce, peach, and apple with a satisfactory recovery range between 98.85 and 102.00%. The obtained results indicated that the newly developed method is stable, convenient, and has easy preparation steps with low-cost materials. It can be used for rapid diagnosis of Zineb in crops and agriculture products, which holds great promise in detection of environmental pollutants.

一种基于分子印迹聚合物/单壁碳纳米管修饰的玻璃碳电极的电化学传感器，用于检测食品样品中的锌杀菌剂

本研究开发了一种基于分子印迹聚合物（MIP）的选择性电化学技术，以简单快速地测定齐尼布杀菌剂。通过原氨基苯酚（o-AP）单体和齐尼布杀真菌剂分析物的电聚合，在用单壁碳纳米管（SWCNT）修饰的玻璃碳电极（GCE）上合成了分子印迹聚合物（MIP）。研究人员将一些离子和化合物作为干扰物，以考察所开发传感器的选择性。这项研究提出了简单测定 Zineb 杀菌剂的方法，其线性范围为 5-1000 fM，检测限 (LOD) 为 1.6 fM。最后，该方法被成功用于检测黄瓜、马铃薯、番茄、莴苣、桃子和苹果等蔬菜和水果样品中的齐奈布，回收率在 98.85% 至 102.00% 之间，结果令人满意。结果表明，新开发的方法稳定、简便，制备步骤简单，材料成本低廉。该方法可用于农作物和农产品中嗪草酮的快速诊断，在环境污染物检测中具有广阔的应用前景。
