- 改性ACFmodified activated carbon fibre
- 經(jīng)氧化、磺化和堿化處理制得了各種氈狀改性ACF，通過(guò)Boehm滴定、氮吸附脫附等溫線(xiàn)和紅外光譜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.
- 經(jīng)濃硝酸和濃過(guò)氧化氫氧化ACF制得的氧化改性ACF,通過(guò)Boehm滴定分析表明氧化改性ACF表面酸性基團明顯增加,也得到了FT-IR和TG的驗證。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.
