摘要

摘要吸附法是利用低成本吸附活性炭去除废水中苯酚的一种环保、经济、有效的技术。研究了苯酚初始浓度、吸附温度和吸附时间对苯酚去除率的影响。苯酚的最大去除率为初始150的63.73% 在25°C下获得的mg/l浓度。Langmuir、Freundlich、Temkin和Dubinin–Radushkevich等温线模型已用于研究吸附平衡。结果表明，Langmuir和Freundlich等温线与平衡数据拟合较好，相关系数（R2）较高，最大吸附量为108.70 毫克/克。吸附动力学数据的完全拟合遵循伪二阶模型。热力学参数是在25–50°C的温度范围内计算的。结果表明，在低温条件下，AC对苯酚的吸附过程更为有利。

Activated carbon from sugarcane as an efficient adsorbent for phenol from petroleum refinery wastewater: Equilibrium, kinetic, and thermodynamic study

Abstract The adsorption method may be one of the environmentally friendly, economical, and effective techniques to remove phenol from wastewater using low-cost adsorbent activated carbon (AC). The effects of the initial concentration of phenol, temperature, and time of the adsorption on the phenol removal percent were studied. The maximum removal percentage of phenol was 63.73% of the initial 150 mg/l concentration obtained at 25°C. Langmuir, Freundlich, Temkin, and Dubinin–Radushkevich isotherm models have been applied to study the adsorption equilibrium. The results show that both Langmuir and Freundlich isotherms fitted the equilibrium data better with a high correlation coefficient (R 2) and a maximum adsorption capacity of 108.70 mg/g. Thorough fitting of adsorption kinetics data followed the pseudo-second-order model. Thermodynamic parameters were calculated in the temperature range of 25–50°C. The results show that the adsorption process of phenol on AC is more favorable at low temperatures.
