Abstract
Waste lubricant oil is mostly produced by its replacement on engines machine, which is frequently discarded into the environment to seawater in particular. Calotropis gigantea and Ceiba pentandra fibres had the potential to be used as a natural oil absorbent material. This study was conducted on these fibres’ oil sorption capacity in artificial seawater, using different variations in the thickness of the oil layer, contact time, mass absorbent, and temperature. The highest sorption capacity was obtained by 65,70 g/g for Calotropis gigantea, 79,71 g/g for Ceiba pentandra on fibre weight of 0.3 g, 9 mm oil film thickness, contact time 60 minutes, at room temperature. This report represents that both fibres are highly effective sorption on waste lubricant oil.
