- 改性ACFmodified activated carbon fibre
- 经氧化、磺化和碱化处理制得了各种毡状改性ACF,通过Boehm滴定、氮吸附脱附等温线和红外光谱分析研究改性前后的ACF。The regeneration of modified ACF was also studied. The above modified felty ACF samples were characterized by Boehm titration, adsorption and desorpotion isotherms of nitrogen at 77K and fourier transform infrared spectroscopy (FT-IR) analysis.
- 经浓硝酸和浓过氧化氢氧化ACF制得的氧化改性ACF,通过Boehm滴定分析表明氧化改性ACF表面酸性基团明显增加,也得到了FT-IR和TG的验证。ACF, oxidized by concentrated nitric acid and hydrogen peroxide, was analyzed by Boehm titration, FT-IR and TG The results of Boehm titration showed the acidic group amount of oxidized ACF increased obviously.
