摘要： 针对城市河道突发溢油污染事件频发，河道内溢油污染快速迁移扩散，以及溢油拦截需联动快速响应的特点，采用3种市场易得、数量充足的纺织纤维材料作为吸油材料，进行了溢油吸附拦截实验研究.本研究探索了棉花、亚麻和大麻纤维对水面浮油的吸附速率、吸附能力以及河水温度对材料吸油能力的影响，并通过拟合分析，得到不同吸油条件下的等温吸附动力学方程；实验还考察了3种纤维材料吸油后油的回用情况.研究结果表明：3种纺织纤维具有较好吸油性能，材料易得，可以作为城市河道突发溢油事件时的快速响应截油材料.

Abstract: Cotton, flax fiber and hemp fiber, three of the most common and aboundant textile fibers, were evaluated as sorbent for treating sudden oil spill pollution. Oil-sorption capacity, sorption rate, reusability of sorbents, and the effect of river temperature were investigated. Sorption kinetic equation was established by curve fitting under the different sorption condition. All of the three textile fibers showed high oil sorption performance from the results and were promising as a rapid respond approach for sudden oil spill treatment of urban river.
