摘　　要：制备了银溶胶作为表面增强活性基底,以此为基础详细研究了BPA的表面增强拉曼光谱(SERS)。研究了促凝剂氯化钠的加入对增强效果的影响。实验结果表明,当BPA乙醇溶液的浓度低至10-7g/mL时,依然可以得到明显的SERS信号。此方法操作简便快捷,无需对样品进行预处理,在BPA的快速检测方面具有很大应用潜力。Silver nanoparticles were prepared as SERS substrate to test BPA. Coagulator-NaCl was added to study the effect on SERS. The results showed that obvious SERS signal was gotten while the concentration of BPA in ethanol was as low as 10^-7g/mL. And due to the simple procedure in sample preparation and pretreatment,this method shows great application potential in rapid test for BPA.
