摘　　要：在10～25℃条件下，研究废报纸对浓度为100～250mg／L甲基蓝溶液的吸附过程，分别采用5种吸附动力学模型和5种平衡吸附等温线模型对实验数据进行了拟合，通过7种误差分析方程进行了吸附模型拟合效果的综合比较。研究结果表明，在用于比较的模型中，Lagergren二阶－1模型和Dubinin-Radushkevich模型分别是最佳的吸附动力学模型和平衡吸附等温线模型，适用于描述废报纸对甲基蓝的吸附过程。In this paper, the adsorption of methyl blue solution with the concentration of 100 to 250 mg/L by using waste newspaper under the temperature of 10 to 25 ℃ is conducted in which five adsorption kinetic models and five adsorption isotherm models are used to fit the experimental data and the fitting effect of the models are evaluated using seven error analysis methods. The result indicates that the Lagergren pseudo-second order-1 model and the Dubinin-Radushkevich model are the best adsorption kinetic model and the best adsorption isotherm model respectively. The adsorption process of methyl blue solution by waste newspaper could be well described by these two models.
