A highly sensitive and rapid method of in-situ surface-enhanced Raman spectroscopy (SERS) combining with electrochemical preconcentration (EP) in detecting malachite green (MG) in aquaculture water was established. Ag nanoparticles (AgNPs) were synthesized and spread onto the surface of gold electrodes after centrifuging to produce SERS-active substrates. After optimizing the pH values, preconcentration potentials and times, in-situ EP-SERS detection was carried out. A sensitive and rapid analysis of the low-concentration MG was accomplished within 200s and the limit of detection was 2.4 × 10M.
建立了一种结合电化学预浓缩（EP）的原位表面增强拉曼光谱（SERS）的高灵敏度和快速方法，用于检测水产养殖水中的孔雀石绿（MG）。通过离心将银纳米粒子（AgNPs）合成并铺展在金电极表面，以产生 SERS 活性衬底。在优化 pH 值、预浓缩电位和时间后，进行了原位 EP-SERS 检测。在 200s 内完成了低浓度 MG 的敏感快速分析，检测限为 2.4×10-7M。
