Spilled oil has been considering as extremely serious disaster in the maritime
field and oil exploration, and its effects lasted for decades, even hundreds
of years. Oil spill treatment and recovery were the difficult and complicated
issues due to the conditions of nature environment. In this work, rice strawagricultural
residue in Vietnam – with 205 k g/m3 of low density was filled in
porous polyurethan matrix in fabrication process of absorbent. The experimental
results about oil absorption capacity for this new absorbent material
showed that, the absorbed oil mass in case of filling 25% of rice straw mass
with 0.5mmof sizewas highest, equal to 12.012 g oil/ g absorbent material after
120 minutes of treatment. The result of oil absorption capacity was around
3–4 times higher than that of material fabricated by pristine polyurethan or
xenlulozo/lignocellulosic. Besides, fabrication process and SEM analysis were
also experimentally carried out in this work.
