Sorption Kinetics and Intra Particulate Diffusivity of Crude Oil on Kenaf (Hibiscus cannabinus L.) Plant Parts

I.A. Okoro, D.E. Okwu and U.S. Emeka    

Abstract: The Kinetics of sorption and intarparticute diffusivity of crude oil using kenaf (Hibiscus cannabinus L.) plant parts was studied. The amount of crude oil adsorbed increased with time. The amount of crude oil adsorbed were 11. 86, 9.92, 7.54 and 7.10 mg mL 1 for the roots and stems respectively. The fractional attainment of equilibrium, values showed that the stem parts research equilibrium point before the root parts. This study has showed that the sorption of crude oil on kenaf (Hibiscus cannabinus L.) plant parts is particle diffusion controlled. The rate coefficient for particle diffusion were 0.015 and 0.007 mm-1 for the root parts and stem parts, respectively.
