Method for the extraction and determination of microplastics in samples of organic and inorganic matrices

摘要

Method for the extraction and the determination of microplastics in samples with organic and inorganic matrices, including the fundamental stages of: sampling and pre-treatment, acid digestion of the sample, extraction of microplastics in liquid phase, identification and quantification of the microplastics; and characterized by the fact of measuring the dimension and counting a plurality of microplastics, as the reading area measures 1 mm2, by means of electronic microscope coupled with energy dispersive X-ray analysis.
