The invention relates to a method for extracting and determining microplastics in samples containing organic and inorganic matrices, comprising the following basic phases: sampling and pretreating, carrying out acid digestion on the sample, extracting the micro plastic in a liquid phase, and identifying and quantifying the micro plastic; and the method is characterized in that when the size of the reading area is 1mm 2 In time, multiple microplastics were measured for size and counted by electron microscopy in conjunction with energy dispersive X-ray analysis. |
