摘要

金属有机框架材料（MOFs）具有高度的比表面积和良好的吸附性能，近年来在环境分析领域得到了广泛应用。本研究提出了一种基于MOFs固相萃取-质谱联用技术（SPE-MS）的方法，用于检测环境水样中的微塑料添加剂。通过MOFs材料的高选择性吸附，结合质谱的高灵敏度检测，能够实现对微塑料添加剂的精确定量。该方法具有较好的分离效率、较低的检测限，并能有效应对复杂水样中的干扰物质。此技术为环境监测提供了一种新颖的解决方案，尤其在微塑料污染的实时监测方面具有重要的应用价值。

Abstract

Metal - organic frameworks (MOFs) have a high specific surface area and good adsorption properties, and have been widely used in the field of environmental analysis in recent years. This study proposes a method based on MOFs solid - phase extraction - mass spectrometry (SPE - MS) technology for the detection of micro - plastic additives in environmental water samples. Through the highly selective adsorption of MOFs materials and the combination with the high - sensitivity detection of mass spectrometry, the precise quantification of micro - plastic additives can be achieved. This method has good separation efficiency, low detection limit, and can effectively deal with the interfering substances in complex water samples. This technology provides a novel solution for environmental monitoring, and has important application value especially in the real - time monitoring of micro - plastic pollution.
