Abstract In this work we report the use of separator pads made of polystyrene nanofibers filled with sawdust for the separation of oil spills. The polystyrene nanofiber membrane was first synthetized using two electrospinning and impregnation methods, and then the synthetized pads were filled with different types of sawdust including willows, poplars and chipboards. The proposed pads were utilized for the separation of oil spills from aqueous solutions. Pre-experiments showed that the poplar sawdust with particle size in the range 40–60 mesh had the highest sorption capacity for the separation of different oil spills. The adsorption capacity of the pads synthetized by the both electrospinning and impregnation methods for the separation of the all types of oil spills decreased with increasing reaction temperature. Moreover, their sorption capacity decreased with increasing pH up to natural pH, and then slightly increased by increasing the solution pH. The results showed that under optimum conditions (reaction temperature = 25 °C, pH = 4, and contact time = 1 min), the adsorption capacities of the proposed pads by impregnation method for the separation of motor oil, diesel oil, furnace oil, and crude oil were 1, 0.63, 0.97 and 0.59 g/g, respectively. Moreover, the adsorption capacities of the pads prepared by electrospinning method for the mentioned oils were 1.41, 1.4, 1.5 and 1.1 g/g, respectively. The synthesized pads made of polystyrene nanofibers and sawdust offered a high efficiency for the removal of different types of oil spills, and therefore they can be used as cheap, available, reusable, eco-friendly and efficient technology for the separation of oil pollution in water aqueous.

木屑填充聚苯乙烯纳米纤维作为分离垫在溢油分离中的应用

摘要 在这项工作中，我们报告了使用填充有锯末的聚苯乙烯纳米纤维制成的分离垫来分离漏油。首先使用两种静电纺丝和浸渍方法合成聚苯乙烯纳米纤维膜，然后在合成的垫中填充不同类型的木屑，包括柳树、杨树和刨花板。建议的垫子用于从水溶液中分离溢油。预实验表明，粒径在 40-60 目范围内的杨木锯末具有最高的分离不同溢油的吸附能力。通过静电纺丝和浸渍方法合成的用于分离所有类型溢油的垫的吸附能力随着反应温度的升高而降低。而且，它们的吸附能力随着 pH 值增加到自然 pH 值而下降，然后随着溶液 pH 值的增加而略有增加。结果表明，在最佳条件下（反应温度 = 25 °C，pH = 4，接触时间 = 1 min），采用浸渍法分离机油、柴油、炉油、和原油分别为 1、0.63、0.97 和 0.59 g/g。此外，通过静电纺丝法制备的垫对上述油的吸附容量分别为1.41、1.4、1.5和1.1 g/g。由聚苯乙烯纳米纤维和锯末制成的合成垫为清除不同类型的漏油提供了高效率，因此它们可以作为廉价、可用、可重复使用、
