摘要
为了解决倍硫磷、对硫磷等有机磷残留检测效率低的难题,提出了一种基于表面增强拉曼光谱的快速检测技术,利用金纳米溶胶作为增强基底,利用便携式拉曼光谱仪作为检测设备,实现了对多种有机磷物质的多点同时检测.实际应用表明,倍硫磷、对硫磷浓度和拉曼谱峰强度有直接关系,能够实现定量精确检测,对倍硫磷的最小检测质量浓度为0.009 μg/L,对硫磷的最小检测质量浓度为 0.02 μg/L,具有检测精度高、速度快、多物质同时检测的优点,实现了对环境中磷残留的现场快速测定.
Abstract
In order to solve the problem of low detection efficiency of organic phosphorus residues such as parathion and parathion,a rapid detection technology based on surface enhanced Raman spectroscopy was proposed.Using gold nanosols as the enhancement substrate and a portable Raman spectrometer as the detection equipment,multi-point simultaneous detection of multiple organic phosphorus substances was achieved.Practical applications have shown that there is a direct relationship between the concentrations of sulfur,parathion,and Raman peak intensity,which can achieve quantitative and accurate detection.The minimum detection mass concentration for sulfur is 0.009 μg/L,the minimum detectable mass concentration of parathion is 0.02 μg/L,which has the advantages of high detection accuracy,fast speed,and simultaneous detection of multiple substances,achieving rapid on-site determination of phosphorus residues in the environment.
