A preliminary study on adsorptibility of different materials on water soluble fraction of tapis blended crude oil

Abstract

This study aims to investigate the effectiveness of four different local materials to remove water soluble fraction of crude oil in water. Four materials used in this study were coconut husk, activated carbon, chitosan and chitin. The adsorption rate for each testing material was determined. The maximum adsorption rate of coconut husks, chitosan, activated carbon and chitin were 0.11 mg.t 1 1 , 0.05 mg.g· 1 .min- .min- 1 1 1 1 1, 0.05 mg.g· .min· and 0.02 mg.g· .min- respectively. Coconut husks exhibit the highest adsorption rate in removing water soluble fraction of crude oil from water. Then followed by chitosan, activated carbon and chitin. All materials used in this study had varies adsorption capacity in adsorbing water soluble fraction of crude oil. The adsorption capacity of coconut husks, chitosan, activated carbon and chitin were 3.03 mg.g· 1 , 1.91 mg.t 1 1 1 , 1.87 mg.g· and 1.02 mg.g· respectively. Coconut husks once again exhibit the highest adsorption capacity followed by chitosan, activated carbon arid chitin
