An effective way to prevent coronavirus (COVID-19) infection is to wear a mask. Accordingly, the demand for masks is increasing, and the number of waste masks was also accelerating. The main component of masks is made of polypropylene (PP). PP has organic solvent or oil adsorption performance due to its low surface energy. In this study, the roughness of the discarded mask surface was increased by using heated solvents (heptane, hexane, and decane) to recycling the disposal mask as an oil adsorbent. According to the type of heated solvent, the crystallinity and contact angle of the mask surface was checked, and the correlation between solvent treatment time and the temperature was analyzed to suggest optimal conditions for preparing the adsorbent. The treated mask shows up to 21 times the adsorption performance of Arabian light crude oil. The produced solvent-treated mask can easily convert a waste mask that is difficult to recycle into an oil adsorbent. |
