摘要

本研究试图使用HNO3浸出-煅烧（600°C/6 h）这种方法是从埃塞俄比亚比绍夫图收获的玉米秸秆中提取的，因为它的倾倒量大，成本低，对环境有负面影响。所得到的复合材料特性，如无定形性质，通过晶界连接，从而产生具有无序形态的团聚结构，并且报道了硅氧烷和硅烷醇基团以及附加官能团的存在。该合成产物应用于合成含油废水（SYOWW）的除油，采用分批模式，最大除油率高达99%。研究结果表明，埃塞俄比亚玉米秸秆作为二氧化硅复合材料生产的替代前体具有潜在的适应性，该复合材料具有可用于清理漏油的潜在吸油能力。

Facile Synthesis of Silica Composites with Oil Sorption Efficiency from a Vital Agricultural Waste of Corn Stalk Cultivated in Bishoftu, Ethiopia

This study is attempted to extract the amorphous silica composites using the combined HNO3 leaching-calcination (600°C/6 h) method from corn stalk harvested in Bishoftu, Ethiopia, owning to its profuse dumping, less cost, and negative environmental implications. The resultant composite characteristics such as amorphous nature are connected via the grain boundary which produces an agglomerated structure that has a disordered morphology, and the presence of siloxane and silanol groups, as well as additional functional groups, is reported. The synthesized product is applied in the removal of oil from synthetic oily wastewater (SYOWW) using batch mode delivering a maximum oil removal of up to 99%. The outcome of the study features the potential acclimatization of the Ethiopian corn stalk as a substitute precursor for the production of silica composites which has a potential oil adsorption capacity that can be used for oil spill cleanup.
