Effective clean-up of oil spills due to their negative environmental and economic impact is of capital importance. Clean-up of oil by sorption is considered one of the most desirable choices, because oil can be completely removed without causing any secondary pollution. Natural organic sorbents had been investigated and developed to control oil products‘ spills. Plant biomass is a renewable resource which can be converted into various materials and energy. Hemp (USO-31), as a textile industry waste, was used as an oil product sorbent material. The present study examines hemp sorption capacity of water using different fractions of hemp raw material to be used in oil/water mixtures. The experimental research revealed that water sorption capacity depends on fraction size and sorption time. The results of water sorption capacity of 2.5 and 5.0 mm after 1440 min were 4.74 and 4.67 g water/g dry sorbent, respectively.
