The aim of this study is to investigate the utilization of silkworm cocoon waste, such as pierced or stained cocoons, as a sorbent material for the removal of motor and vegetable oils from water. The oil-sorption capacity, rate and reusability of the material were evaluated. The results show the high sorption capacity of the silkworm cocoon waste sorbent (42-52 g(oil)/g(sorbent) for motor oil and 37-60 g(oil)/g(sorbent) for vegetable oil). The oil sorbed onto the material could be recovered by squeezing the sorbent, and the squeezed material showed an oil-sorption capacity over 15 g(oil)/g(sorbent). We concluded that the material shows a high performance as a low cost and environmental friendly sorbent for the removal of oil from water.
本研究的目的是调查蚕茧废料，如穿孔茧或染色茧，作为从水中去除机油和植物油的吸附材料的利用情况。评估了该材料的吸油能力、速率和可重复使用性。结果表明，蚕茧废料吸附剂具有较高的吸附能力（对机油为42 - 52克（油）/克（吸附剂），对植物油为37 - 60克（油）/克（吸附剂））。吸附在材料上的油可以通过挤压吸附剂回收，挤压后的材料显示出超过15克（油）/克（吸附剂）的吸油能力。我们得出结论，该材料作为一种低成本且环保的从水中去除油的吸附剂表现出高性能。
