Fabrication of high efficiency coronavirus filter using activated carbon nanoparticles.

In this study design and fabrication of coronavirus filter based on the cellulose and carbon nanomaterials have been investigated. Particulate matter (PM) corona virus has attracted a lot of attention due to its great threat to human health. Nanoparticles are intertwined with fibers and form highly porous air filter paper. The structure of the filter has been characterized using scanning electron microscope (SEM) and Brunauer-Emmett-Teller (BET) analysis. In addition, by optimization with activated carbon (AC) nanoparticles, the prepared AC air filter paper shows a high removal efficiency of more than 95% for PM 100 nm. More importantly, this filter shows less pressure drop and less thickness. This filter has a positive effect on the prevention of this disease during the coronavirus epidemic and show high absorption efficiency air filter for PM more than 100 nm.
