Here, we present an adapted NanoRelease protocol for a UV-dose-dependent assessment and size-selective quantification of the release of micro- and nanoplastic fragments down to 10 nm and demonstrate its applicability for polyamide and thermoplastic polyurethanes.
15 de sept. de 2021 · This review summarized the current MPs degradation techniques such as AOPs and biodegradation, degradation mechanism, and development status and gave some recommendations for future research directions on the basis of the proposed knowledge gaps.
1 de ago. de 2023 · Microplastic degradation corresponds to the key concepts of the circular economy by terminating the cycle of plastic waste. Microplastics can be effectively degraded into useful products or feedstocks to manufacture new plastics, minimizing the need for virgin materialsand fostering an improved lifespan.
15 de mar. de 2023 · Microplastics are a type of synthetic polymer with a particle size of<5 mm that are found in various environments.
24 de nov. de 2021 · Advanced oxidation processes (AOPs) are emerging techniques for MP purification. Herein, a hydrothermal coupled Fenton system is developed for decomposition of ultrahigh-molecular-weight polyethylene, achieving 95.9% weight loss in 16 h and 75.6% mineralization efficiency in 12 h.
14 de oct. de 2020 · Mechanical degradation of microplastic debris mainly occurs through abrasion whereby the particles come into contact with natural and other anthropogenic items in aqueous and terrestrial settings.
30 de sept. de 2021 · Microplastic waste is an emerging global issue due to its environmental effect of accumulation in ecosystems, and waste managing systems have given rise to its presence in the aquatic environment. It is gaining attention due to its persistent nature and potential adverse effects on living organisms.
