Carbonized peanut shell (CPS), a low cost adsorbent was investigated for adsorption of methylene blue from its aqueous solution. Some experimental parameters like the effect of initial dye concentration, initial solution pH, phases contact time and temperature were investigated. Langmuir, Freundlich and Harkins-Jura isotherm models were applied to the experimental data and Langmuir model fitted best. Monolayer adsorption capacity was 5.34 mg/g according to the Langmuir model. Adsorption capacity/uptake of CPS was found comparable to the some other adsorbent materials. The kinetic and intra particle diffusion models were applied to the experimental data. The experimental reaction was progressed via pseudo second order kinetic model. The thermodynamic parameters were also evaluated.
碳化花生壳（CPS）作为一种低成本吸附剂，用于从水溶液中吸附亚甲基蓝。研究了一些实验参数，如初始染料浓度、初始溶液pH值、相接触时间和温度的影响。将朗缪尔、弗伦德利希和哈金斯 - 朱拉等温线模型应用于实验数据，结果表明朗缪尔模型拟合效果最佳。根据朗缪尔模型，单层吸附容量为5.34 mg/g。发现CPS的吸附容量/吸附量与其他一些吸附剂材料相当。将动力学和颗粒内扩散模型应用于实验数据。实验反应通过准二级动力学模型进行。还评估了热力学参数。
