摘要:
基于表面增强拉曼光谱方法(surface-enhanced raman spectroscopy,简称SERS)与快速溶剂提取前处理技术,建立茶叶中乐果农药残留的快速检测方法。以金纳米粒子为增强基底,分别采集不同浓度乐果溶液的表面增强拉曼光谱和不同浓度以茶叶提取液为基质的乐果溶液表面增强拉曼光谱;采用无水硫酸镁、四氯化三铁、石墨化碳对提取液进行净化处理,去除基质中叶绿素、矿物质、茶多酚、碳水化合物等物质的干扰;762、902、1 050、1 160、1 210、1 310、1 653 cm-1这7处谱峰可作为鉴定乐果农药的峰。结果表明,茶叶中乐果农药最低浓度能达到1.0 mg/L以下;对不同浓度以茶叶提取液为基质的乐果溶液表面增强拉曼光谱进行分析,发现762 cm-1处特征峰强度与乐果浓度在 1~10、8~25 mg/L内具有良好的线性关系;配制3个浓度样本验证方法的准确度,平均回收率为93.89%~96.36%,相对标准差为2.59%~4.87%,均小于5.00%,说明用该方法检测茶叶中的乐果农药具有较高的准确度和精密度。
