表面增强拉曼技术在茶叶农药残留检测中的研究进展
|
摘要
茶叶是世界上重要的经济作物,其消费和饮用遍布全球各地,因此,茶叶的质量安全备受人们的关注。农药残留是茶叶质量安全最重要的问题之一。传统的检测方法往往具有步骤复杂,耗费时间长,成本高且不能现场检测的缺点而无法完全满足现实检测的需求。愈来愈高的贸易壁垒迫切需求新的检测方法的出现。表面增强拉曼光谱技术(surface enhanced Raman scattering, SERS)因其选择性强、灵敏度高、无损检测等优点吸引着研究者们的目光。茶叶农药残留的SERS检测前处理技术是非常重要的一步,不同的茶叶农药需要不同的前处理方法。良好的衬底能够大大提高拉曼增强检测的灵敏度。先进的算法可以优化拉曼光谱的处理,提高检测准确度。因此,本文主要总结了SERS技术在茶叶农药残留检测方面的概况,阐述相关技术难点、解决方案及发展趋势,为茶叶农药残留的快速检测技术提供新的思路和方向。
Tea is an important cash crop in the world, which is consumed and drunk all over the world. Therefore,the quality and safety of tea products attract human's attention. Pesticides residues is one of the most significant problem of tea products. Traditional detection methods often have the disadvantages of complicated steps, long time consuming, high cost and no on-site detection, so they cannot fully meet the requirements of practical detection.Increasingly high trade barriers call for new testing methods. Surface enhanced Raman scattering(SERS) is so attractive to researchers because of its strong selectivity, high sensitivity, and non-destructive inspection. It is a very important step to apply the SERS detection and pretreatment technology for tea residue. Different tea pesticides require different pretreatment methods. A good substrate can greatly improve the sensitivity of Raman enhanced detection. The advanced algorithm can optimize the processing of Raman spectrum and improve the detection accuracy. This paper mainly summarized the general situation of SERS technology in the detection of pesticide residues in tea and elaborated the technical difficulties, solutions and development trends, providing new ideas and directions for the rapid detection technology of tea pesticide residues.
