Metallized Nanofibrous Filter for Repeatable Dead-end Filtration and Following Degradation of Captured Microplastics

Popis výsledku v původním jazyce

This paper focuses on the filtering of microplastics from wastewater and qualitative and quantitative analysis of filtered microplastics. Nanofibrous layers are now widely used for air and water filtration mainly due to the low production cost and high filtration effectivity of low grammage materials. However, the mechanical and malleable properties of nanofibrous layers are very poor. An industrial sputter coater was used to metallize the nanofibrous layer by zero-valent metals (copper, chromium, nickel). The metallization with pure metals, rather than oxides or hydroxides, is supposed to improve the mechanical properties of the nanofibers. This method further enhances the contamination of filtered water by plastics from the nanofibrous layer itself. Moreover, the metallization shields the FTIR spectrum of polymerous nanofibers, which makes it possible for the filter to be used for qualitative analysis of microplastics stuck on the filter without the spurious filter spectrum background. The chemical and physical degradation of captured microplastics is also included in this research, describing plasma and inorganic oxidation reagents.
