OIL ADSORBENT, OILY WATER TREATMENT METHOD, OILY WATER TREATMENT FILTER, AND OILY WATER TREATMENT DEVICE
To provide an oil adsorbent which has high oil adsorbability, can be easily recovered when sprayed onto the water surface, and has a small environmental load at the time of discarding.SOLUTION: An oil adsorbent 1 comprises a granular adsorbent substrate 2 made of an organic porous body, and a water repellent material 3 coated and/or impregnated with the adsorbent substrate and giving lipophilicity and water repellency to the adsorbent substrate 2. When the adsorbent substrate 2 including the water repellent material 3 and water are mixed and shaken for two hours, and then allowed to stand for 20 minutes, the ratio (w/w) of the adsorbent substrate including the water repellent material, floating on the water surface, is 90% or more.SELECTED DRAWING: Figure 1
【課題】油の吸着性が高く、水面に散布した際の回収が容易で、しかも廃棄処分時に環境への負荷が小さい油吸着材を提供する。【解決手段】有機性の多孔質体からなる粒状の吸着基材２と、この吸着基材にコーティング及び／又は含浸され、かつ吸着基材２に親油性及び撥水性を付与する撥水材３と、を備え、この撥水材３を備えた吸着基材２と水とを混合して２時間振とうしてから２０分間静置した場合に、水面に浮遊している撥水剤を備えた吸着基材の割合（ｗ／ｗ）が９０％以上である油吸着材１による。【選択図】図１
