Project Title Chemically modified pomelo pith for oil sorption
Synopsis Oil spills have posed an enormous threat towards the marine ecosystem and cause water pollution. Current oil spill removal methods include using dispersants and boomers and skimmers. Such methods are often limited in effectiveness and expensive. This study proposes to improve the oil sorption capacity of pomelo pith by chemically modifying it. Pomelo pith was treated with methyltrimethoxysilane (MTMS) and oleic acid to increase its hydrophobicity and with sodium hydroxide to increase its surface area. The treated pomelo piths were characterised by Scanning Electron Microscope (SEM) and water contact angle. Sorption capacity of the pomelo pith in various liquids (oil, water & oil-water) was also investigated. Chemical treatment with MTMS, oleic acid and sodium hydroxide successfully increase the oil sorption capacity of pomelo pith in pure oil environment. However in the oil-seawater environment, only oleic acid treated and MTMS treated pomelo pith outperformed the untreated pomelo, with the MTMS treated pomelo pith exhibiting the greatest oil sorption capacity, absorbing oil up to almost 8 times its weight.(168 words)
