Abstract
Romanian Merino wool was tested as a natural sorbent for oil spill cleanup. Rebco crude oil placed in distilled water was used as an oily water model. Experiments of batch sorption were performed under various conditions. The effects of process factors, i.e., initial density of packed bed sorbent (0.05-0.99 g/cm3), initial volume ratio of oil and water (0.25 and 0.14 cm3/cm3), and contact surface between adsorbent and oily water, on wool sorption capacity (6.4-11.8 g/g) were evaluated. Experimental data were fitted using pseudo-first order rate and pseudo-second order rate models. Keywords: oil spill, kinetic model, sorption capacity, wool fibre

Summary
Romanian Merino wool was tested as a natural sorbent for oil spill cleanup. Rebco crude oil placed in distilled water was used as an oily water model. The effects of process factors, i.e., initial density of packed bed sorbent (0.05-0.99 g/ cm3), initial volume ratio of oil and water (0.25 and 0.14 cm3/cm3), and contact surface between adsorbent and oily water, on wool sorption capacity (6.4-11.8 g/g) were evaluated. E.g., acrylic resins, polyurethane foams, polypropylene and polyester fibres, are the most used sorbents for oil removal and recovery [2,4,5,11]. They possess good oleophilic and hydrophobic properties, but are non-biodegradable and generally expensive [1-5,11]. The effects of process factors in terms of initial density of packed bed sorbent, initial volume ratio of oil and water, and contact surface between adsorbent and oily water were evaluated
