Portable device and method for extracting microplastics from plateau lake sediments

Abstract

The invention discloses a portable device and method for extracting micro-plastics from plateau lake sediments, and relates to the technical field of micro-plastic separation and extraction. The problems that in the existing treatment process, a plurality of devices need to be used for synergistic effect to achieve the separation purpose, the process is tedious, and the devices are not easy to carry are solved. The portable device comprises a PVC bottom plate, a first PVC pipeline is arranged at the upper end of the PVC bottom plate, a ball valve is installed at the upper end of the first PVC pipeline, a second PVC pipeline is installed at the upper end of the ball valve, an aluminum foil top cover is installed at the upper end of the second PVC pipeline, and connecting bases are arranged at the connecting positions of the ball valve and the first PVC pipeline and the second PVC pipeline correspondingly. And first threaded structures are arranged on the inner wall of one end of the first PVC pipeline and the inner wall of one end of the second PVC pipeline correspondingly, and the first threaded structures, the first PVC pipeline and the second PVC pipeline are integrally formed.

Description

technical field [0001] The invention relates to the technical field of separation and extraction of microplastics, in particular to a portable device and method for extracting microplastics from plateau lake sediments. Background technique [0002] Microplastic pollution in the environment is becoming one of the most serious threats to the entire Earth's surface ecosystem. In recent years, more and more studies have shown that inland lakes and rivers, like the ocean, are facing serious microplastic pollution problems, and lakes are an important "sink" of microplastic pollution in inland water bodies. 0.1 / m3 to thousands / m3, reaching or even exceeding the level of microplastic residues in the ocean reported by the same sampling method. Plateau lakes are important channels for the transmission of terrestrial microplastics to rivers and oceans. Compared with marine sediments, the research on microplastic pollution in plateau lake sediments is still in its infancy, mostly focu...
