Abstract
In this study, groundnut husk particles were used to remove Escravos crude oil from seawater surface in order to assess their sorption potentials. The investigations were carried out using five different particle size ranges (4000-1000, 1000-500, 500-105, 105-53 and <53 μm) of the husk on three different oil layer thicknesses (3, 4.5 and 6 mm) over water. The particles sorbed crude oil to different degrees and at different rates but no uptake of water by the husk particles were observed. The initial sorption rates of the sorbent in the first ten minutes were the highest with the three oil layer thicknesses investigated. The maximum oil sorption capacity recorded was 9.8442g oil/g sorbent at forty minutes by particle C (500-105 μm) with 3 mm oil layer. This sorption performance compares fairly well with extant literature results for a commercial sorbent and other raw lignocellulosic plant wastes such as corn husk and kapok. The fairly good oil sorption results recorded by the particles, with no water sorption, under a dynamic experimental condition used in this work is indicative of good oleophilic property and potentials as a biosorbent. The empirical oil sorption kinetic model of raw groundnut husk particles was of inverse (decaying) exponential form which indicates a diffusion sorption mechanism.
