【摘要】：利用氨水對(duì)預(yù)處理過(guò)的玉米芯進(jìn)行改性,研究改性玉米芯對(duì)活性艷紅(K-2BP)染料的吸附行為。通過(guò)傅里葉紅外光譜對(duì)改性玉米芯進(jìn)行結(jié)構(gòu)表征,并考察了pH值、吸附時(shí)間、溫度和初始濃度對(duì)活性艷紅K-2BP吸附性能的影響及其吸附動(dòng)力學(xué)性質(zhì)。結(jié)果表明,在pH值1.61、溫度30℃和吸附時(shí)間10 h條件下吸附效果較佳,其飽和吸附量為22.936 mg·g~(-1),吸附行為符合Langmuir吸附等溫線,反應(yīng)級(jí)數(shù)符合準(zhǔn)二級(jí)反應(yīng)動(dòng)力學(xué)特征,反應(yīng)活化能為17.655 k J·mol~(-1)。
[Abstract]:The modified corncob was modified with ammonia to study the adsorption behavior of the modified corncob to reactive brilliant red K-2BPP. the structure of the modified corncob was characterized by Fourier transform infrared spectroscopy (FTIR). The effects of pH, adsorption time, temperature and initial concentration on the adsorption properties of reactive brilliant red K-2BP and its adsorption kinetics were investigated. The adsorption effect was better at 30 鈩，
