Abstract
In this study, the fabrication of stainless steel mesh coated with polypyrrole nanocomposite and graphene oxide (Ppy-GO) by electropolymerization via cyclic voltammetry (CV) is presented for the first time. The surface of the stainless steel mesh was modified by the hydroxide group. Then electropolymerization of pyrrole (Py) was done on the surface of functionalized steel mesh in the medium of sodium dodecyl sulfate (SDS) as a counter ion pump in dehydrated oxalic acid. The seven main effective extraction parameters including type of extraction solvent, mesh size, sample volume, volume of extraction solvent, type of absorbent, adsorption time and extraction time, were investigated and optimized according to Taguchi’s method. The results of the experimental design show that type of extraction solvent and volume of extraction solvent have the most significant effect on the extraction process. Field-emission scanning electron microscope imaging (FESEM) and Fourier transform infrared spectroscopy (FT-IR) confirmed the characterization of the homogenous and porous surface of the sorbent. Ultimately, under the optimized conditions, the proposed method was used for extraction of acrylamide (AA) from potato chips samples and relative recoveries were obtained in the range of 92 to 100.5%. This method showed the linearity in the range of 0.5 to 70 µg mL − 1 with coefficient of determination 0.9974, limit of detection of 0.1 µg mL − 1 and limit of quantification 0.5 µg mL − 1 for acrylamide. Moreover, good repeatability (RSD% 2.19–3.9) was obtained. The extraction is carried out by direct immersion in the sample dispersed in water through the microextraction method followed by a gas chromatography-flame ionization detector (GC-FID), successfully.
本研究首次采用循环伏安法（CV）电聚合法制备了聚吡咯纳米复合材料和氧化石墨烯（py- go）涂层的不锈钢网。用氢氧化物基团对不锈钢网表面进行了改性。然后以十二烷基硫酸钠（SDS）作为反离子泵，在脱水草酸中对功能化钢网表面进行吡咯（Py）的电聚合。根据田口法对提取溶剂类型、筛孔大小、样品体积、提取溶剂体积、吸收剂类型、吸附时间和提取时间等7个主要有效提取参数进行了考察和优化。实验设计结果表明，萃取溶剂的种类和萃取溶剂的体积对萃取过程的影响最为显著。场发射扫描电镜（FESEM）和傅里叶变换红外光谱（FT-IR）证实了吸附剂表面的均匀性和多孔性。最终，在优化条件下，将该方法用于薯片样品中丙烯酰胺（AA）的提取，相对回收率为92 ~ 100.5%。该方法在0.5 ~ 70 μ g mL - 1范围内呈线性关系，测定系数为0.9974，丙烯酰胺的检出限为0.1 μ g mL - 1，定量限为0.5 μ g mL - 1。重复性好（RSD% 2.19 ~ 3.9）。采用气相色谱-火焰离子化检测器（GC-FID），将分散于水中的样品直接浸没在微萃取法中，提取成功。图形抽象
