一种高效的油吸附剂，由香烟过滤嘴制成，使用低复杂性，单步工艺生产。这样做是为了解决石油污染和香烟过滤器垃圾的双重问题。油的吸附能力被发现的电纺醋酸纤维素吸附剂，由原生醋酸纤维素和香烟过滤嘴。不仅香烟过滤嘴衍生的吸附剂具有比在其他研究中发现的吸附剂更高的油吸附能力（具有93.7g/g的能力），而且吸附剂还使用不太复杂和能量密集度较低的方法生产。另外，发现香烟过滤嘴吸附剂的油吸附能力高于原始乙酸纤维素吸附剂的油吸附能力。这被认为是由于添加剂，甘油三乙酸酯（GA），发现在香烟过滤嘴。这意味着从香烟过滤嘴中采购醋酸纤维素不仅可以解决香烟过滤嘴污染，而且还可以生产更有效的吸附剂。因此，在本研究中产生的香烟滤嘴衍生的油吸附剂具有成为一种高效且更可持续的油污染修复解决方案的潜力。
A highly effective oil sorbent, made from cigarette filters, was produced using a low complexity, single-step process. This was done to address the dual issues of oil pollution and cigarette filter litter. The oil sorption capacity was found for electrospun cellulose acetate sorbents, made from both virgin cellulose acetate and cigarette filters. Not only did the cigarette filter derived sorbent have a higher oil sorption capacity than sorbents found in other studies (with a capacity of 93.7 g/g), but the sorbent was also produced using a less complex and less energy-intensive method. Additionally, the oil sorption capacity for the cigarette filter sorbent was found to be higher than that of a virgin cellulose acetate sorbent. This was thought to be due to the additive, glycerol triacetate (GA), found within the cigarette filters. This means that not only does sourcing the cellulose acetate from cigarette filters tackle cigarette filter pollution, but it also produces a more effective sorbent. Therefore, the cigarette filter derived oil sorbent produced in this study has the potential to be a highly effective, and more sustainable, solution for the remediation of oil pollution.
