摘要/Abstract

摘要： 采用质量分数分别为17%、34%和68%的硝酸溶液对竹炭进行8 h的表面改性处理,测定了改性前后竹炭的碘值、灰分和水分含量。结果表明:3种改性条件下竹炭的碘值和灰分含量均比改性之前有小幅度下降,而水分含量则比改性之前有明显上升, 其中,以68%硝酸改性的竹炭其各项指标变化幅度最大。使用Boehm滴定法和傅里叶变换红外光谱FTIR对硝酸改性前后的竹炭进行了结构表征,结果发现硝酸改性后的竹炭表面含氧官能团数量有不同程度的增加; 比表面积和孔径分析表明,硝酸改性后竹炭的比表面积显著下降,平均孔径显著增大; SEM-EDS分析表明硝酸改性后竹炭的表面粗糙程度增加,同时含碳量降低,含氧官能团数量增加; TG-DSC分析结果同样表明硝酸改性后的竹炭表面有大量水分子和表面官能团生成,进而造成失重率显著增加。

Abstract: Nitric acid with different concentrations(17%, 34%, and 68% respectively)was employed to modify the bamboo charcoal, and the iodine value, ash and water content of raw and modified bamboo charcoal samples were measured. Test results showed that the iodine value and ash content of three kinds of modified bamboo charcoal decreased slightly, while the water content of three kinds of modified bamboo charcoal samples increased sharply, the bamboo charcoal sample modified with 68% nitric acid has the most remarkable change of these above values. The Boehm titration,FTIR,BET,SEM-EDS and TG-DSC were used to characterize raw and modified bamboo charcoal samples. The results showed that the amount of different kinds of oxygen-containing groups increased on the surface of modified bamboo charcoal samples, while the carbon content decreased evidently,the surface of modified bamboo charcoal became more tough than the raw bamboo charcoal, and the slope of weight loss curves of modified bamboo charcoal were more successive and steeper than that of the raw bamboo charcoal,which showed that a great number of H₂O molecules and surface functional groups were formed on the surface of modified bamboo charcoal.
