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

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.
