Effect of agitation on sorption behavior of expanded graphite for methyl orange in water and crude oil floated on water

摘要

Expanded graphite was used for absorbing methyl orange in water and crude oil floated on water. The effect of agitating sorption system including crude oil or methyl orange, water and expanded graphite on the sorption behavior of expanded graphite for the two materials was investigated, and the sorption mechanism of expanded graphite for the two materials was discussed. The results show that agitating sorption system is advantageous for the methyl orange sorption, but disadvantageous for the crude oil sorption.
