Chemically modified pomelo pith for oil sorption

Yang Xiang, Roy Luo, Sheng Hao Ong, Singapore 16-18

Oil spills result in negative impacts on the environment such as depleting oxygen supply and polluting water bodies. Current methods of resolving oil spills are inefficient and not environmentally friendly. Our project aims to chemically modify pomelo pith, a natural waste, as an oil sorbent. We would be using three different chemical modifications: methyltrimethoxysilane (MTMS), oleic acid, and mercerization. After the chemical modification, we will characterize our sorbent’s hydrophobicity (ability to repel water) and oleophilicity (ability to attract oil) by determining its water sorption capacity and oil sorption capacity in pure oil, pure water, and oil-seawater environments.
