Not only marine species, but human and nature environment have been also affected seriously as the marine environment is polluted by oil spill, heavy metal, and others. In this study, a new sorbent fabricated by adding rice straw into polyurethane foams was investigated. Oil types such as crude oil, fuel oil, diesel oil, kerosene and a solution containing Cd2+, Cu2+ metal ion were used to evaluate the absorption capacity of this new sorbent. The experimental result after 150 minutes showed that, the oil absorption capacity of new sorbent added 25% of rice straw mass and 500 m of size was highest, correspondingly to 15.086 g/g, 13.964 g/g, 12.226 g/g, 10.746 g/g of crude oil, fuel oil, diesel oil, kerosene, respectively. Moreover, Cd2+, Cu2+ metal ion absorption capacity was 212.9 mg/l and 193.6 mg/l. Besides, the relationship between contact angles and pore diameters, oil absorption capacity and oil surface tension, SEM were considered.
