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

将绿色材料用于石油回收应用是要实现的目标，以减少这些基本过程对环境的影响。在这种情况下，Arundo Donax L. 是一种以其广泛用途而闻名的植物，之前已经对其吸收特性进行了研究。在本文中，评估了硅烷表面处理对从这种环保且具有成本效益的材料的秆中提取的天然纤维的吸收行为的影响。通过微观结构和形态分析，已确定所研究油的物理特性与纤维尺寸之间存在密切对应关系。吸水量是自身重量的 6 到近 8 倍，同时提高了污染物/水吸收的选择性，取得了优异的效果，
