摘要
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。
The sorbents used to collect oil in case of oil-spills are commonly synthetic materials that are usually of diffi-culty in decomposition. In this study, we compared the capacities and rates of the fibre, a by-product of peat excavation, and mats made from peat adsorbing several types of rock oil with a synthetic, commercially available oil sorbent. The results showed that the fibre was superior in absorbing oil, approximately two to three times higher in adsorbing quan-tity and rate than that of the commerc...
