  • 摘要: 通过实验室培养实验模拟生物质炭的老化过程，探索不同材料制备的生物质炭老化前后对多环芳烃（菲）吸持作用的影响，利用扫描电镜与傅里叶变化红外光谱等技术探究生物质炭老化前后的结构变化.结果表明，生物质炭老化过程中会形成老化层，550 ℃热解条件下，两种材料制备的生物质炭老化后含氧量增加、CEC增加，对菲的吸附能力均增强，主要与老化后表面羧基减弱和脂肪族官能团增加有关，而老化后稻壳炭的吸附能力更强与醚键的显著增加有关.
    Abstract: The aging of biochar produced from different pyrolysis materials was simulated through laboratory incubation to explore the effects of this process on the adsorption of phenanthrene. The structure before and after aging was characterized by diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) and scanning electron microscopy (SEM) techniques. The results demonstrated that an "aging layer" was formed on the biochar surface after aging process. Oxygen content, cation exchange capacity (CEC), and phenanthrene adsorption capacity also increased after aging due to the decrease of carboxyl groups and the increase of aliphatic contents. The higher adsorption capacity of rice husk carbon compared to the straw carbon is probably associated with the higher contents of the ether bonds on its surface.
