Scientific Development Research

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.
