Solid phase extraction (SPE) is a consolidated technique for determining pollutants in seawater samples. The current tendency is to miniaturise systems that extract and determine pollutants in the environment, reducing the use of organic solvents, while maintaining the quality in the extraction and preconcentration. On the other hand, there is a need to develop new extraction systems that can be fitted to in situ continual monitoring buoys, especially for the marine environment. This work has developed a first model of a low-pressure micro-SPE (m-SPE) for persistent organic pollutants (POPs) that can be simply applied to in situ monitoring in the marine environment. This system reduces the volumes of sample and solvents required in the laboratory in comparison with conventional SPE. In the future, it could be used in automated or robotic systems in marine technologies such as marine gliders and oceanographic buoys. This system has been optimised and validated to determine polycyclic aromatic hydrocarbons (PAH) in seawater samples, but it could also be applied to other kinds of persistent organic pollutants (POPs) and emerging pollutants.
固相萃取（SPE）是一种用于测定海水样品中污染物的成熟技术。当前的趋势是使环境中污染物的萃取和测定系统小型化，减少有机溶剂的使用，同时保持萃取和预浓缩的质量。另一方面，需要开发能够适配原位连续监测浮标的新型萃取系统，特别是针对海洋环境。这项工作开发了一种用于持久性有机污染物（POPs）的低压微型固相萃取（m-SPE）的首个模型，该模型可简单应用于海洋环境的原位监测。与传统固相萃取相比，该系统减少了实验室所需的样品和溶剂量。未来，它可用于海洋技术中的自动化或机器人系统，如海洋滑翔器和海洋学浮标。该系统已针对测定海水样品中的多环芳烃（PAH）进行了优化和验证，但它也可应用于其他种类的持久性有机污染物（POPs）和新兴污染物。
