摘要: 为了对木屑这种天然生物质作为吸附材料进行研究,采用碱性双氧水对其进行改性并研究其吸油性能。通过实验,比较了不同改性溶液浓度以及不同改性时间的吸油量,发现经1% H2O2 浸泡改性18 h后,改性木屑(HNCS)的吸附能力大大提高,吸油量达9.4 g·g-1,而改性前仅为6.47 g·g-1,改性使得吸油量提高了45%。同时研究了改性木屑对不同油品的吸油性能的测定,结果显示改性木屑对原油的吸附效果最好。通过扫描电镜(SEM)、热重失重分析以及红外扫描光谱分析研究了改性木屑的物化性能。发现经改性后,木屑的表面更加粗糙,出现了大量的吸附孔隙,且热稳定性提高,表面的亲水基团减少。说明吸油量受到材料内部的孔隙结构,以及表面官能团的影响。

Abstract: The purpose of this work was to study the oil absorption capacity of sawdust,a kind of natural biomass material.H2O2 and NaOH were used to modify sawdust and to research the oil-adsorbing properties of the modified material.Through experiments,oil absorption of sawdust was compared for varying periods of modification.After an 18 h modification,the oil absorption of HNCS was 9.4 g·g-1.Compared with sawdust 6.47 g·g-1,the oil absorption capacity increased by 45%.Comparison of HNCS on the adsorption properties of organic compounds toluene and vegetable oil,the adsorption effect of the crude oil is better than vegetable oil and toluene.Scanning electron microscopy(SEM),thermal gravimetric analysis(TGA),and infrared spectroscopy were used to study the physical and chemical properties of the modified sawdust.The results showed that the surface roughness of HNSD increased,the cellulose content was increased and hydrophilic functional groups were reduced.The results indicated that the oil sorption capacity was influenced by the surface area and pores of the adsorbent.
