石油是现代工业世界的重要能源之一。它必须通过海洋和内陆运输从生产地运送到全球许多地方。在运输过程中，由于意外事故或战争期间的故意行为，石油有可能在水体上溢出，从而造成环境污染。由结构纤维制成的吸附剂被认为是清理溢油的最佳材料。吸附剂的吸油和滞留行为受吸附剂的材料、结构和油的物理特性的影响。为了环境的可持续发展，使用过的吸附剂的处理是一个主要问题。在此背景下，天然可降解材料比合成材料具有更大的潜力。本文综述了溢油的清理，重点介绍了吸油现象、溢油清理方法、吸油剂材料的特性、纤维材料中的流体流动、制备吸油剂的纤维材料类型以及吸油剂的测试方法。
Oil is one of the important sources of energy in the modern industrial world. It has to be transported from the source of production to many places across the globe through oceans and inland transport. During transportation the chance of oil spillage over the water body occurs due to accidents or by deliberate action during war time and this causes environmental pollution. Sorbents made from structured fibre assembly are found to be the best material to clean up oil spill. The oil sorption and retention behavior of sorbents are influenced by the material and structure of the sorbents and oil physical characteristics. For sustainable environment, disposal of used sorbents is a major issue. In this context, the naturally available biodegradable materials have great potential than the synthetic ones. This paper reviews about oil spill cleanup with special emphasis on the phenomenon of oil sorption, methods of oil spill cleanup, characteristics of oil sorbent materials, fluid flow through fibrous materials, types of fibre materials envisaged for making sorbents and test methods for oil sorbents.
