摘要

以火力发电厂固体废弃物粉煤灰为研究对象，采用吸附法成功地去除了水中的2,4-二甲基苯酚。在达到平衡之前，吸附速率遵循一级动力学。扩散阻力和动力学阻力都影响吸附速率，它们的相对影响随操作温度的变化而变化。平衡吸附数据同时满足Langmuir和Freundlich等温线。

Kinetics and mechanism of removal of 2, 4-dimethyl phenol from aqueous solutions with coal fly ash

Coal fly ash, a solid waste from thermal power stations was used to successfully remove 2,4-dimethyl phenol by adsorption from aqueous solutions. The rate of adsorption follows first order kinetics before attaining equilibrium. Both diffusional and kinetic resistances affect the rate of adsorption and their relative effects vary with operating temperatures. Equilibrium adsorption data satisfied both Langmuir and Freundlich isotherms.
