中文摘要：本文制备了一种新型表面增强拉曼光谱阵列，该阵列通过提供增强光谱建立了一种快速、简单、经济的农药残留检测方法。本文对新型表面增强拉曼光谱阵列的表现和稳定性进行了表征。分别对含有10、0.01和0.01 mg/L的吡虫啉、啶虫脒和噻菌灵农药残留浓度的水溶液进行检测，新型表面增强拉曼光谱基板的活性为5个月。本文还利用该技术对果蔬和废水样本进行检测，苹果和马铃薯中噻菌灵农药残留浓度为0.5 mg/kg，并在废水中检测出了啶虫脒农药残留。研究结果表明，该基板在果蔬农药残留的快速检测方面具有较大的潜力，并可应用于废水质量检查。
外文摘要：A new surface-enhanced Raman spectroscopy (SERS) array is easily fabricated that offers strong enhancement with rapid, simple, and inexpensive detection. A gold nanoparticle-functionalized glycidyl methacrylate-ethylene dimethacrylate suspension was prepared to fabricate SERS arrays with an injection procedure in large quantities. The performance and stability of SERS arrays were characterized. Pesticides of imidacloprid, acetamiprid, and thiabendazole in aqueous solution were determined at concentrations of 10, 0.01, and 0.01 mg L-1, respectively. The SERS activity of the substrate endured for 5 months. Thiabendazole was determined at 0.5 mg kg(-1) in apples and potatoes and acetamiprid in wastewater with SERS arrays. This substrate may have potential for use in rapid monitoring of pesticides on fruits and vegetables and allow quality inspection of wastewater.
