Abstract
Abstract The use of masks is very important to reduce transmission of the COVID 19 virus. Therefore, an innovation is needed from mask materials is that are environmentally friendly, have good filtration quality and have anti-virus agents. An alternative way to provide masks with good filterability using a raw material of cellulose acetate. Cellulose acetate has fibrils that are bonded together so that it can form dense fibers. Fiber is a semipermeable layer that functions as a particle filtration. Therefore, this study aims to get cellulose from corn husks via delignification. The research method consisted of extracting cellulose from corn husks and further synthesizing cellulose acetate. FTIR results showed an absorption peak at wave numbers 3349 cm -1 , 1728 cm -1 , 1252 cm -1 , and 1031 cm -1 . These peaks indicated the presence functional groups of OH, C=O, aryl ether, and C-O. This functional group indicates a cellulose acetate compound.
