The waters and wastewaters around industrial areas are heavily polluted and have adverse effects on the ecosystems. The present study is mainly focused on the electropolymerization of ortho-phenetidine and co-deposited on a steel wire along with graphene oxide nanosheets as a novel coating for solid-phase microextraction of polycyclic aromatic hydrocarbons (PAHs) from aqueous media prior to gas chromatography-mass spectrometry. PAHs are composed of multiple aromatic rings which have been linked to skin, lung, bladder and liver. Cancer is a primary human health risk of exposure to PAHs. To obtain a firm and stable coating, several empirical factors relevant to the electrochemical process were investigated. Characterization for chemical structure and surface morphology of the synthesized nanocomposite was conducted with FT-IR spectroscopy and FE-SEM, respectively. XRD and TGA were applied to study the other properties of the nanocomposite. Some essential items involved in microextraction process were also checked in details. Under optimized case, validation parameters were assessed. Wide linearity (0.005–5.0 ng mL⁻¹), low detection limits (0.4–4.3 pg mL⁻¹) and good repeatability (3.6–9.5%) and reproducibility (7.6–11.8%) were achieved. The developed method was utilized to analyze contaminated real samples such as wastewater samples from coal processing industries and agricultural water samples collected from the vicinity of the industry in different seasons and high recoveries were obtained, finally.

工业区周围的水和废水受到严重污染，对生态系统产生不利影响。目前的研究主要集中在邻位的电聚合-乙炔吡啶并与氧化石墨烯纳米片一起共沉积在钢丝上，作为在气相色谱-质谱分析之前从水性介质中固相微萃取多环芳烃（PAH）的新型涂层。PAH由多个芳香环组成，这些芳香环已与皮肤，肺，膀胱和肝脏相连。癌症是暴露于PAHs的主要人类健康风险。为了获得牢固稳定的涂层，研究了与电化学过程相关的几个经验因素。分别用FT-IR光谱和FE-SEM对合成的纳米复合材料的化学结构和表面形态进行表征。XRD和TGA被用于研究纳米复合材料的其他性能。还详细检查了微萃取过程中涉及的一些重要事项。在优化的情况下，评估验证参数。宽线性度（0.005–5.0 ng mL^-1），低检测限（0.4–4.3 pg mL ^-1）和良好的重复性（3.6–9.5％）和重现性（7.6–11.8％）。所开发的方法用于分析受污染的真实样品，例如来自煤炭加工业的废水样品和在不同季节从该行业附近收集的农业水样品，从而获得了高回收率。
