摘要

本文揭示了使用隔膜的超声波喷射雾化技术能够将水中的微塑料包裹成雾状，并将其排放到空气中。特别是，雾化雾的大小与雾中包裹的丙烯酸颗粒之间存在很强的相关性：平均直径为 1.5 μm 或更小的丙烯酸颗粒被选择性地包裹在平均直径为 2.2 μm 的雾化雾中。这一结果表明，喷射雾化技术能够从众多不同直径的微颗粒中选择直径为 1.5 μm 或更小的颗粒，并将它们分离成单个颗粒，而不会发生聚集。这项研究的结果可用于分析分散在河流、湖泊和海洋中的微塑料，从众多不同直径的微粒中分离出目标直径的微粒，而不会出现聚集现象。

A selective separation method for microplastics using ultrasonic jet atomization

This paper reveals that ultrasonic jet atomization using a diaphragm enables the enclosure of microplastics in water into atomized mist, emitting them into the air. In particular, a strong correlation is found between the sizes of the atomized mist and the acrylic particles enclosed in the mist: Acrylic particles with an average diameter of 1.5 μm or smaller are selectively enclosed within the atomized mist with an average diameter of 2.2 μm. This result indicates that jet atomization has the ability to select particles with diameters of 1.5 μm or less from numerous micro-particles with different diameters and separate them into individual particles without aggregation. The results of this study can be applicable to the process of analyzing microplastics dispersed in rivers, lakes, and oceans for separating particles of a targeted diameter from numerous particles of different diameters without aggregation.
