Surface Modified Arundo Donax Natural Fibers for Oil Spill Recovery

ABSTRACT

The use of green materials for oil recovery applications is the goal to be achieved to reduce the environmental impact of these essential processes. In this context, Arundo Donax L. is a plant known for its wide uses whose absorbent properties have been previously investigated. In this paper, the influence of silane surface treatment on the absorbent behavior of natural fibers extracted from the culms of this eco-friendly and cost-effective material was assessed. A close correspondence has been identified between the physical characteristics of the investigated oil and the fiber size, by means of microstructural and morphological analysis. Excellent results have been achieved with an absorption uptake of six to almost eight times its own weight, coupled with an improved selectivity of pollutant/water absorption, making the surface modified Arundo Donax fibers a potential effective material for oil recovery applications.

摘要

在石油开采应用中使用绿色材料是为了减少这些基本工艺对环境的影响. 在此背景下, Arundo Donax L.是一种用途广泛的植物, 其吸收性能此前已被研究过. 在本文中, 评估了硅烷表面处理对从这种生态友好且成本效益高的材料的秆中提取的天然纤维的吸附性能的影响. 通过微观结构和形态分析, 确定了所研究油的物理特性与纤维尺寸之间的密切对应关系. 由于吸收率为其自身重量的六到八倍, 加上污染物/吸水选择性的提高, 已经取得了优异的效果, 使得表面改性的Arundo-Donax纤维成为潜在的有效采油材料.

Highlights

Modification of Arundo Donax fiber by silanization.

Improved selectivity toward oil was highlighted due to surface silanization

AD silanized fiber has maximum oil sorption capacity of almost 770 wt.%

AD fiber is a suitable sustainable material in the oil sorption process.
