过去用来收集石油避免溢油的吸附剂大都是人工合成的,这就限制了吸附剂降解处理的可能性。我们研究了泥炭开采副产品——羊胡子草纤维、羊胡子草毡片对几种类型石油的吸收能力和速率,并把它们同人工合成的商业石油吸附剂作比较。发现羊胡子草纤维具有优良的吸收性能:羊胡子草吸附剂吸收石油量大约是合成吸附剂的2～3倍,速度也是它的2～3倍;在测试中羊胡子草纤维几乎不吸水,这使它成为从水表面吸附石油的理想吸附剂;去除水面柴油时效率超过了99%,等于吸附剂自身重量的20倍。试验证明了生物所能降解的羊胡子草纤维是一种效率高、原料成本低的石油吸附剂。
In the past, the adsorbents used to collect oil and avoid oil spills were mostly synthetic, which limited the possibility of adsorbent degradation. We investigated the absorptive capacity and rate of several types of oil for the by-products of the peat mowing - Paeonia lactiflora and Panerai Felt - and comparing them with synthetic commercial petroleum adsorbents. Cotton flax grass fiber has excellent absorption properties: Cotton flax grass adsorbent absorbs about 2 to 3 times the amount of synthetic adsorbent, its speed is also its 2 to 3 times; in the test, Cotton flax grass fiber almost no water, This makes it an ideal adsorbent for the adsorption of oil from the water surface; removing more than 99% of the efficiency of surface diesel oil equals 20 times the weight of the adsorbent itself. Experiments show that the biodegradable Ramulus beard grass fiber is a high efficiency, low cost of raw materials, petroleum adsorbent.
