Using aerogels from coconut fiber for treating oil and grease

Abstract

Water pollution by oil and grease always causes serious damage to the ecological environment and human health. Biodegradable aerogels from coconut fiber were synthesized by using polyvinyl alcohol (PVA) as a linker and freeze-drying method. This environmentally friendly aerogel has low density (0.0575 g/cm3) and high porosity (96.24%). Aerogels from coconut fiber have hydrophobic properties. If these aerogels are coated with methytrimethoxysilane (MTMS), their maximum oil adsorption capacity will reach 20.2 g/g. This study’s findings showed that it is feasible to use aerogels for treating oil and grease.
Keywords
