摘要
本文以玉米秸秆为原料,通过水热法制备了水热炭材料,并利用SEM及红外光谱(FTIR)对水热炭形貌与结构进行了表征。随后本研究考察了光照对水热炭去除罗丹明B(RhB)性能的影响,同时探究了光源种类、反应气氛等环境因素对水热炭去除RhB性能的贡献。实验结果表明:水热炭表面具有多孔褶皱结构,且富含含氧官能团。同时,光照能在420 min内将水热炭去除RhB(20 mg/L)的去除率从65.9%提升至100%;此外,紫外光与溶解氧对水热炭去除RhB有重要贡献,而溶解性有机碳会显著抑制RhB的光降解过程。
In this study,hydrothermal carbon(HTC)was prepared via hydrothermal method using corn straw as raw material,and then SEM and FTIR were used to the characterize the morphology and surface functional groups of HTC.Subsequently,the effect of light on rhodamine B(RhB)removal performance by hydrothermal carbon was investigated,and the contribution of environmental factors,including light source type and reaction atmosphere,to rhodamine B removal performance by hydrothermal carbon were studied.SEM and FTIR results revealed that porous fold structure and oxygen-containing functional groups were found on the surface of HTC.By comparing the RhB removal efficiency by HTC in the presence and absence of light,it was found that light enhanced RhB removal percentage from 65.9%to 100%within 420 min.Moreover,UV light and dissolved oxygen played positive role in RhB removal by HTC,while dissolved organic carbon would inhibit the degradation of RhB by light.
