【摘要】：利用氨水对预处理过的玉米芯进行改性,研究改性玉米芯对活性艳红(K-2BP)染料的吸附行为。通过傅里叶红外光谱对改性玉米芯进行结构表征,并考察了pH值、吸附时间、温度和初始浓度对活性艳红K-2BP吸附性能的影响及其吸附动力学性质。结果表明,在pH值1.61、温度30℃和吸附时间10 h条件下吸附效果较佳,其饱和吸附量为22.936 mg·g~(-1),吸附行为符合Langmuir吸附等温线,反应级数符合准二级反应动力学特征,反应活化能为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，
