Plastic pollution is one of the major environmental problems of the 21st century, with recent evidence highlighting potential risks to terrestrial and marine ecosystems. Plastics degrade over time due to various environmental stresses, producing plastic particles such as microplastics (100 nm-5 mm in size) and nanoplastics (<100 nm). In particular, nanoplastics leaked into the ocean can cause marine pollution, and when aquatic organisms ingest organic pollutants, their toxicity can affect humans through the food chain. In general, microplastics are removed through physical removal (membrane filter, etc.) and chemical removal (adsorption, coagulant, etc.). In this study, a biosolvent is utilized to induce aggregation of polystyrene nanoparticles. Accelerate the dissolution of the polystyrene nanoparticles surface with a bio-solvent and increase the attachment efficiency with the freeze-thaw process for agglomeration and precipitation. |
