Abstract

The study that has been carried out is synthesis of activated carbon and titanium dioxide composite on pineapple leaf fiber for application in respiratory mask. The composite was prepared by mixing activated carbon and TEOS with titanium dioxide in nitric acid solution. Activated carbon and titanium dioxide composite was coated in pineapple leaf fiber with dip coating methods. The composite was applied in the respiratory mask. UV LED was added on the respiratory mask as the UV light source for photocatalytic reaction. The surface morphology of synthesized composite was characterized by microscope with 400x magnifications. The adsorption of respiratory mask with activated carbon and titanium dioxide composite and N95 respiratory mask were evaluated by gas analyzer.  The results shown that respiratory mask with N95 adsorb CO, HC, and CO2 within 12.12%, 5.6%, and 21.05%. While activated carbon and titanium dioxide composite mask adsorb CO, HC, and CO2 gas as much as 60.61%, 55.6%, 63.13%. It has been found that the respiratory mask with activated carbon and titanium dioxide composite has higher adsorption ability than N95 respiratory mask.
