Abstract

Medical mask waste is part of the covid waste that can threaten the living creatures and environment since it was pathogenic and indestructible. Moreover, the waste management of medical mask waste is still ineffective due to the limit of technology and resource. The purpose of this review is to learn the potency of medical mask waste as the main component of nanofiber fabrication. This review is using the literature review method. There are some fundamental stages for creating nanofiber from polypropylene of medical mask waste, such as pre-treatment, making polypropylene solution, fabrication, and characterization. Removal of medical mask waste contaminants can be using a chemical solvent, dry heat, or exposure to ultraviolet C. Type of solvent plays a principal role in producing polypropylene solvent that is ready to fabricate. On the industrial scale, electrospinning is a commonly used method for nanofiber fabrication. The characterization of the fiber and pore size can be analyzed with scanning electron microscope (SEM) analysis, material crystallinity using x-ray diffraction (XRD) spectroscopy, and thermogravimetric analysis (TGA) measuring the thermal stability of nanofiber.

Abstract

 Bangka Belitung Islands Province faces severe environmental challenges, exacerbated byillegal tin mining activities leading to heightened pollution levels, particularly in stagnantwater within former tin mining holes, reaching depths of up to 40 meters. The presence ofiron metal (Fe) in this water poses a health risk, potentially damaging intestinal walls andcompromising lung function upon ingestion. This study presents a novel approach to addressthis issue by synthesizing porous carbon material from propylene waste sourced frommedical masks. The process involves initial sulfonation for sterilization and pore sizeenhancement, followed by activation using KOH and carbonization at 750 °C.Characterization methods validate the successful synthesis, including FTIR highlightingpolypropylene groups at 822 cm-1, XRD indicating graphite carbon with high crystallinity,and SEM exhibiting rod shapes and cavities at 5,000í— magnification. The adsorption testdemonstrates outstanding performance, with porous carbon exhibiting a 100% adsorptionefficiency in purifying water, eliminating odors, and reducing iron (Fe) levels. Thisinnovative method effectively reduces iron levels in stagnant water environments, providinga sustainable solution to environmental pollution, particularly in Bangka Belitung.
